Question

Solve the following equation for the unknown quantity: 12x-8=3x+10. a. x=4 b. =2 c =12 d. x=1/2

Answer 1

b. x=2

Explanation:

Step 1- Move the variable to one side.

12x-8= 3x+10

-3x -3x

9x-8= 10

Step 2- Add 8 to both sides.

9x-8= 10

+8 +8

9x= 18

Step 3- Divide to both sides.

9x= 18

9 9

x= 2
