6 + 3x = 12 x - 15
Which value for x makes this equation true: 7/3, 3/7, 5/7 , or 7/5

x = 7/3

Step-by-step explanation:

Step 1: Write equation

6 + 3x = 12x - 15

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

6 + 3(7/3) = 12(7/3) - 15

6 + 7 = 28 - 15

13 = 13

  x = 7/3

Step-by-step explanation:

  6 +3x = 12x -15

  9x = 21 . . . . . add 15-3x

  x = 21/9 . . . . . divide by 9

  x = 7/3
