Answer:
w = 7
Step-by-step explanation:
w + 4(6 + 2w) = 87
- distribute the 4
w + 24 + 8w = 87
- combine like terms
9w + 24 = 87
- subtract 24 from both sides
9w = 63
- divide 9 from both sides
w = 7
Answer:
Step-by-step explanation:
11) add 20 to both sides, x=-3
12) divide both sides by -8, v=18
13) divide both sides by -7, n=19
14) multiply both sides by 9, n=171
