Answer:

x = -3

Step-by-step explanation:

To solve:

Simplify: -2x+7x is 5x, and -12-3 is -15. 5x=-15 is the new equation, divide by 5 and x is -3.

Answer:

X=-3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

-2x+3+7x=-12

(-2x+7x)(3)=-12(combine like terms)

5x+3=-12

Step 2: Subtract 3 from both sides.

5x+3-3=-12-3

5x=-15

Step 3: Divide both sides by 5.

5x/5=-15/3

X=-3
