-7q + 2 = 11q - 8q
-7q + 2 = 3q
-7q + 7q = 2 = 3q + 7q
2 = 10q
divide both sides by 10 and reduce
8(j - 3) = 4j + 9j - 14
8j - 24 = 13j - 14
8j - 24 + 14 = 13j - 14 + 14
8j - 10 = 13j
8j - 8j - 10 = 13j - 8j
-10 = 5j
divide both sides by 5 and reduce to solve for j
-7q + 2 = 3q
-7q + 7q = 2 = 3q + 7q
2 = 10q
divide both sides by 10 and reduce
8(j - 3) = 4j + 9j - 14
8j - 24 = 13j - 14
8j - 24 + 14 = 13j - 14 + 14
8j - 10 = 13j
8j - 8j - 10 = 13j - 8j
-10 = 5j
divide both sides by 5 and reduce to solve for j
