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
Answer:
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
