Answer:
-4 y + 11 x + -22
Step-by-step explanation:
Simplify the following:
3 x - 4 (y + 3) - 10 + 8 x
Hint: | Group like terms in 3 x - 4 (y + 3) - 10 + 8 x.
Grouping like terms, 3 x - 4 (y + 3) - 10 + 8 x = -4 (y + 3) + (3 x + 8 x) - 10:
-4 (y + 3) + (3 x + 8 x) - 10
Hint: | Add like terms in 3 x + 8 x.
3 x + 8 x = 11 x:
-4 (y + 3) + 11 x - 10
Hint: | Distribute -4 over y + 3.
-4 (y + 3) = -4 y - 12:
-4 y - 12 + 11 x - 10
Hint: | Group like terms in -4 y + 11 x - 12 - 10.
Grouping like terms, -4 y + 11 x - 12 - 10 = -4 y + 11 x + (-12 - 10):
-4 y + 11 x + (-12 - 10)
Hint: | Evaluate -12 - 10.
-12 - 10 = -22:
Answer: -4 y + 11 x + -22
