So first you distribute. So it would be 2x+7= 3x-12. Then you wanna get the variables on one side. So you subtract 2 from both sides. 7=x-12. Now you wanna get the numbers on one side. So you add 12 on both sides. 19=x. So x=19

Answer:

x=19

Explanation:

Step 1: Simplify both sides of the equation.

2x+7=3(x−4)

2x+7=3(x−4)

2x+7=(3)(x)+(3)(−4)(Distribute)

2x+7=3x+−12

2x+7=3x−12

Step 2: Subtract 3x from both sides.

2x+7−3x=3x−12−3x

−x+7=−12

Step 3: Subtract 7 from both sides.

−x+7−7=−12−7

−x=−19

x=19
