What is the solution to 7x+115=136?

x=3

Step-by-step explanation:

In order to solve this kind of equation, you need to be able to understand what the question is asking. This question is asking what value of X will make both sides equivalent to each other?

In order to find out, you need to get X by itself.

The first step is to subtract 115 from both sides.

7x+115=136

-115  |  -115

7x=21

Now, the X value is by itself with another value on the other. With this part, you need to divide both sides by 7.

7x=21

/7 | /7

x=3

This is because you have 7 X's and you need to have only 1 of the X's.
