Answer 2

oh sorry 3a+10+4(a+2) -1/2 a

Answer 3

3a+10=4(a+2) -1/2 a OK THATS THE RIGHT ONE

Answer 4

okay

Answer 5

3a + 10 = 4(a+2) - 1/2
Divide everything by 4:
(3/4) a + 10/4 = a+2 - 1/8

Answer 6

Subtract (3/4) a from both sides:
10/4 = (1/4)a + 2 - 1/8

Answer 7

10/4 = (1/4)a + 15/8 (im just simplifying the right side)

Multiply thru by 4:
10 = a + 15/2
Subtract 15/2 from both sides:
5/2 = a
