ok so it could be 2 things
(3/4)x=1/8 or
3/(4x)=1/8
if it is (3/4)x=1/8, go to AAAAAAAAAAAAA
if it is 3/(4x)=1/8 go to BBBBBBBBBBBB
AAAAAAAAAAAAA
(3/4)x=1/8
multiply both sides by 4/3 to clear fraction ( since 3/4 times 4/3=12/12=1)
1x=4/24
x=1/6
BBBBBBBBB
3/(4x)=1/8
multiply both sides by 4x
3=(4x)/8
multiply both sides by 8
24=4x
divide bohs ides by 4
6=x
if it is (3/4)x=1/8, then x=1/6
if it is 3/(4x)=1/8, then x=6
