Answer:

a = 3.6

Step-by-step explanation:

2/3(6a + 9) = 20.4

Distribute 2/3

4a + 6 = 20.4

Subtract 6 from both sides

4a = 14.4

Divide by four on both sides

a = 3.6

Answer:

a=3.6

Step-by-step explanation:

then simplify, 4a+ 6=20.4

bring the 6 to the other side. 4a=14.4

simplify. a=3.6
