How do you get the equation to 6x+12=2(×+12)

DedPeter [7]

Answer:

x = 3

Step-by-step explanation:

Simplify 2(x+12)

6x+12=2x+24

Move all terms containing x to the left side of the equation. 4 x + 12 = 24

Move all terms not containing x to the right side of the equation. 4 x = 12

Divide each term by 4 and simplify. x = 3
