Question

12x+12=3x+84 so what does x=​

Answer 1

Answer: Answer: x=8

Explanation:

12x+12=3x+84

Subtract 12 on both sides:

12x+12-12=3x+84-12

12x=3x+72

Subtract 3x on both sides:

12x-3x=3x-3x+72

9x=72

Divide 9 on both sides:

9x/9=72/9

x=8

Answer 2

x = 8

Explanation:

12x +12 = 3x +84

12x +12 -12 -3x = 3x -3x +84 -12

12x -3x = 84 -12

9x = 72

9x/9 = 72/9

x = 8
