2A = 3 (8 + 4A) Multiply by 3 on both sides. Cancel out 3 at left side.
2A = 24 + 12A Distribute 3.
2A/2 = (24 + 12A)/2 Divide by 2 on both sides.
A = 12 + 6 Cancel 2 at left side. Divide 24 and 12 by 2 on right side.
A - 6A = 12
-5A = 12
A = 12/-5
A = -2 2/5

First multiply by 3 to get 2A = 24 + 12A. Then you simplify to (2A - 12A) = 24 which then equals -10A=24 and then A=24/(-10) = -2.4 and so solving the equation: A = - 2.4

2A/3=8 + 4A => subtract 4A from both sides
2A/3 - 4A = 8 =>
2A/3 - 12A/3 = 8 =>
-10A/3 = 8 =>
-10A = 24 =>
A = -2.4

To get rid of the three in 2A/3, multiply each side by three: 2A = 24 + 3(4A). Then divide both sides by two: A= 12 + 1.5(2A).
That's how I would do it.

2A/3 = 8 + 4A multiply x3 on both sides
2A = 3(8+4A) distribute the 3 into the parenthesis
2A=24+12A substract 12A on both sides
2A -12A = 24 simplify the left side
-10A = 24 divide by -10
A = -24/10 =-2.4

2A/3 = 8 + 4A
A = (8+4A) X 3/2
a = -2
