Question

What are the steps and answer to 5x + 12 - 7x = -3 (5x + 8)

Answer 1

x= −36 /13

Explanation:

Step 1: Simplify both sides of the equation.

5x+12−7x=−3(5x+8)

5x+12+−7x=(−3)(5x)+(−3)(8)(Distribute)

5x+12+−7x=−15x+−24

(5x+−7x)+(12)=−15x−24(Combine Like Terms)

−2x+12=−15x−24

−2x+12=−15x−24

Step 2: Add 15x to both sides.

−2x+12+15x=−15x−24+15x

13x+12=−24

Step 3: Subtract 12 from both sides.

13x+12−12=−24−12

13x=−36

Step 4: Divide both sides by 13.

x= −36 /13
