Answer:

x = 7/5 or 1.4

Explanation:

12x - 15 = 6 - 3x Need to move one variable term to the other side to

+3x + 3x isolate it on one side

---------------------------

15x - 15 = 6 need to +15 to isolate the variable term

+15 +15

-----------------------

15/15x = 21/15 (simplify 21/15 = 7/5) need to divide by 15 to isolate x

------------------------

x = 7/5 or 1.4

Answer:

x= 21/15

if you need to reduce it would be x=7/5

Explanation:

12x-15 =6-3x

add 3x to both sides

15x- 15 = 6

now add 15 to both sides

15x = 21

lastly divide both sides by 15

x= 21/15

if you need to reduce it would be x=7/5
