2A / 3 = 8 + 4A
3(2A/3) = 3(8) + 3(4A)
2A = 24 + 12A
2A - 2A = 24 + 12A - 2A
0 = 24 + 10A
0 - 24 = 24 + 10A - 24
- 24 = 10A
- 24/10 = 10A / 10
- 24/10 = A
- 2.4 = A

2A/3 = 8 + 4A
2A = 3 * (8 + 4A)
2A = 3 * 8 + 3 * 4A
2A = 24 + 12A
2A-12A = 24
(When the term +12A goes to the other side of the equation its sign changes from + to -)
-10A = 24 (on adding +2A -12A = -10A)
A = (24) / (-10)
A = -2.4

2A/3 =8+4A
2A/3-4A =8 multiply all the equation by 3
2A-12A = 24
-10A = 24
A= -2.4
proof -2* 2.4/3 = 8 -4*2.4
-1.6 = 8-9.6=-1.6

2A = 3(8 + 4A)
2A = 24 + 12A
-24 = 10A
A = -24/10
A = -2.4

2A/3 = 8 + 4A
Multiply both sides by 3
2A = 24 + 12A
Combine terms
-10A = 24
A = -2.4

2A/3 = 8 + 4A
10A/3=-8
A=-8*3/10=-12/5
