Question

Solve and check the following equation using inverse operations. -20 = 5 ( x + 1)

You must show all work.

Answer 1

x=-5 or just -5

STEP BY STEP EXPLANATION

ok, so the equation is -20=5(x+1), so first you do the distributive property and your new equation should be -20=5x+5

Then you subtract 5 from both sides and your new equation should be -25=5x

Then you divide 5 from both sides and your final answer should be x=-5 or -5

CHECH YOUR WORK

To check your work just plug in -5 into the equation, so -20=5(-5+1)

-20=5(-4) and the final equation is -20=-20. So the answer of -5 is correct

hope this helped!
