what do x equal -15+3x=7

Question

i need help on this math problem for school

Answer 1

Hi Marciera, to solve this problem, it is necessary to isolate the x term on one side of the equal sign and the numbers on the other side of the equal sign.

 

Start by adding 15 to both sides of the equation. This gives:

 

-15 + 15 + 3x = 7 + 15

 

Combine terms gives:

 

3x = 22

 

To find the value of x, divide both sides by 3.
