Answer:
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
