-4 (5y + 5) = -120
multiply the bracket by -4
(-4)(5y)=-20y
(-4)(5)=-20
-20y-20=-120
move -20 to +20
-20y-20+20=-120+20
-20y=-120+20
-20y=-100
divide both sides by -20 to get y by itself
-20y/-20=-100/-20
Answer: y=5
Answer:
Step-by-step explanation:
-4(5y + 5) = -120
-4*5 y = -20 y
-4*5 = 20
-20 y + 20 = -120
-20 -20
______________
-20 y -100
-20 y -20
y=50
