2A%2F3+=+8+%2B+4A+
multiply both sides of the equation by 3
3%2A%282A%2F3%29+=+3%2A8+%2B+3%2A%284A%29
2A+=+24+%2B+12A
subtract 2A from both sides
2A+-+2A+=+24+%2B+12A+-+2A
0+=+24+%2B+10A
subtract 24 from both sides
0+-+24+=+24+-+24+%2B+10A
-24+=+10A
divide both sides by 10
-%2824%2F10%29+=+A
A+=+-2.4 answer
check answer:
2A%2F3+=+8+%2B+4A+
2%28-2.4%29%2F3+=+8+%2B+4%28-2.4%29+
-4.8+%2F3+=+8+-+9.6
-1.6+=+-1.6
OK
