Answer:

a=20

Step-by-step explanation:

4a+8-2a-3=45

-8 on both sides

4a-2a-3=37

+3 on both sides

4a-2a=40

2a=40

a=20

Answer:

a = 20

Step-by-step explanation:

Let's understand it quickly,

4a + 8 - 2a - 3 = 45

Gather the like terms on RHS and LHS,

4a - 2a = = 45 - 5

2a = 40

a = 40/2

a = 20
