Answer:

12a

12a = 96

Step-by-step explanation:

12a + (6a + 8) + (10a - 4) + (6a + 8) = 204

Combine like terms.

34a + 12 = 284

34a + 12 - 12 = 284 - 12

34a = 272

34a ÷ 34 = 272 ÷ 34

a = 8

Let's replace a and see.

6a + 8

6(8) + 8

48 + 8

56

12a

12(8)

96

10a - 4

10(8) - 4

80 - 4

76
