Answer is 60 U need to calculate carefully with brackets involving multiplication
Answer:
-9y + 5x + 3
Step-by-step explanation:
-8y - (4x - 3) - y + 9x:
Group like terms = -(4x - 3) -8y - y + 9x
Add similar Elements - 8y - y + 9x = - (4x - 3) - 9y + 9x
Apply the distributive law: - (a - b) = -a + b = - (4x -3) = -4x + 3
= 4x + 3 - 9y + 9x
Group like terms = -9y - 4x + 9x + 3
Add similar Elements -4x + 9x = 5x
= -9y + 5x + 3
