Question

Solve the equation -6(2a + 7) = -22- 8a

Answer 1

Answer: a = -5

Step-by-step explanation:

First, open up the brackets, and solve it

-12a -42 = -22 -8a. (-6 x 2a, and -6 x 7)

bring the -8a to the left side, so that all the a’s are together

-12a -42 + 8a = -22 (add -42 on both sides like we did with -8a)

-12a + 8a = -22 + 42

solve

-4a = 20

divide -4 on both sides

a = -5

Step 1

-6(2a + 7) = -22- 8a  Equation/Question

Step 2

-6(2a + 7) = -22- 8a  Remove parenthesis

-12a-42=-8a-22

Step 3

-12a-42=-8a-22  Add 8a to the sides

-4a-42=-22

Step 4

-4a-42=-22  Subtract 42

4a=20

Step 5

4a=20  Divide both sides by 4

answer

-5
