## Solving word problems

These can be very helpful when you're stuck on a problem and don't know how to Solve word problems. There are a few apps that purport to do your homework for you. I haven't tried any of them, but I imagine they would be of limited use. Even if the app could give you the answer to a problem, it wouldn't be able to teach you how to work through the problem on your own. So, while an app that does your homework might save you a bit of time in the short run, it's not going to be very helpful in the long run.

For example: Factoring out the variable gives us: x = 2y + 3 You can also solve exponents with variables by using one of the two methods that we introduced earlier in this chapter. For example: To solve this, we’ll use the distributive property of exponents and expand both sides, giving us x = 2y + 3 and y = 2x. So when we plug these into our original equation, we get x – 2y = 3, which simplifies to y = 3x – 1. That is, when we divide the top and bottom of an exponent by their respective bases, we get a fraction with a whole number on one side. This means that all pairs of numbers that have the same base have the same exponent so that they cancel each other out and leave just one number in their place (that is, a whole number). So for example, 5x + 1 = 6x – 4; 5x – 1 = 6x + 4; and 6x + 1 = 5

Imagine being able to simply take a picture of a math word problem and have the answer pop up on your screen almost instantaneously. That's what one new app promises to do. The app, called PhotoMath, uses the camera on your smartphone or tablet to take a picture of a math problem and then displays the answer. Just point your camera at a problem and PhotoMath will do the rest. The app can solve problems ranging from simple addition and subtraction to more complex equations involving fractions and decimals. It can even handle problems that require multiple steps, such as long division. And if you're not satisfied with the answer it gives you, PhotoMath also provides step-by-step instructions for how to solve the problem. PhotoMath is still in its early stages, so it doesn't always get things right. But it shows promise as a tool that could one day make solving math problems a breeze. So if you're struggling with a math problem, why not give PhotoMath a try? It just might be the answer you're looking for.

Natural log equations can be tricky to solve, but there are a few tried-and-true methods that can help. . This formula allows you to rewrite a natural log equation in terms of a different logarithmic base. For example, if you're trying to solve for x in the equation ln(x) = 2, you can use the change of base formula to rewrite it as log2(x) = 2. Once you've rewriting the equation in this form, it's often easier to solve. Another approach is to use substitution. This involves solving for one variable in terms of the other and then plugging that value back into the original equation. For instance, if you're trying to solve the equation ln(x+1) - ln(x-1) = 2, you could start by solving for ln(x+1) in terms of ln(x-1). Once you've done that, you can plug that new value back into the original equation and solve for x. With a little practice, solving natural log equations can be a breeze.

Another common method is to use graphing. This can be helpful if the inequality is complex and difficult to solve algebraically. In either case, it is important to be careful and to make sure that the solution is
