Answer:
-13 a - 12 b
Step-by-step explanation:
Simplify the following:
-5 (b + 3 a) + 2 a - 7 b
Hint: | Distribute -5 over b + 3 a.
-5 (b + 3 a) = -5 b - 15 a:
-5 b - 15 a + 2 a - 7 b
Hint: | Group like terms in -5 b - 7 b + 2 a - 15 a.
Grouping like terms, -5 b - 7 b + 2 a - 15 a = (-5 b - 7 b) + (-15 a + 2 a):
(-5 b - 7 b) + (-15 a + 2 a)
Hint: | Combine like terms in -5 b - 7 b.
-5 b - 7 b = -12 b:
-12 b + (2 a - 15 a)
Hint: | Combine like terms in 2 a - 15 a.
2 a - 15 a = -13 a:
Answer: -13 a - 12 b
