What value of x makes this equation true? 12x - 15 = 6 - 3x *

x = 1.4 (or 21/15)

Step-by-step explanation:

12x - 15 = 6 - 3x

+3x              +3x

15x - 15 = 6

      +15  +15

15x = 21

/15   /15

x = 21/15  or

x = 1.4

x= 1.4

Step-by-step explanation: To find the value of x that makes the equation true, you have to first simplify it:

12x - 15 = 6 - 3x

15x = 21

x = 21/15

x = 7/5

x = 1 2/5

x = 1.4

i think that you should ask google for the answer to that problem because if we don't know it google does
