How do you I find the answer to x plus 29 equals 87?

Answer 1

First, it'll help you to understand what "answer" means. The "answer" is the number

that 'x' must be in order to make your equation a true statement. There's only one

number that can do that.

Here's an easy way to find it:

x + 29 = 87

What do you have to do to the left side to get 'x' all alone ?

Whatever it is, do the same thing to each side.

Subtract 29 from each side:

x = 87 - 29

x = 58
