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
