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

2a/3 = 8 + 4a
Multiply equation by 3
threfore 2a = 24 + 12 a
– 10a = 24
a = – 24/10 = – 2.4

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

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

Multiply the whole equation by 3
6a=24+12a
6a-6a=24+12a-6a
0=24+6a
-24=24-24+6a
-4=a

2a/3-4a=8
2a/3-12a/3=8
2a-12a=24
-10a=24
-a=24/10
a=-2.4
