Question

Explain to another student how to solve the equation.

Answer 1

Solve for X ( The question I did was an example )

Explanation:

To solve and equation like 2x+9=30 you will have to isolate the number with a variable. You need to subtract 9 on both sides for that to happen.

2x=21

Now the next step is to divide. You have to divide to get the answer.

x=21/2

x= 10.5
