Answer:
a = -32
Step-by-step explanation:
3a−(10+5a)=54
Distribute the minus sign
3a−10-5a=54
Combine like terms
-2a -10 = 54
Add 10 to each side
-2a-10+10 = 54+10
-2a = 64
Divide by -2
-2a/-2 = 64/-2
a = -32
Answer:
a = -32
Step-by-step explanation:
3a - (10 + 5a) = 54
Distribute the negative sign as if it were -1.
3a - 10 - 5a = 54
Combine like terms on left side.
-2a - 10 = 54
Add 10 to both sides.
-2a = 64
Divide both sides by -2.
a = -32
