Answer:
well if the x is in the fraction the answer is 
x=5 
if it is not and it's after the fraction 
x=1/5 
Explanation:
for x=5 for x=1/5 
Apply;fraction:cross:multiply: 8/12=10/3 x then switch sides
8*3x =12*10 10/3 x = 8/12 cancel the common factor:4
simplify: 10/3 x = 2/3 
24x=120 multiply both sides by 3 
divide both sides by 24 3*10/3 x = 2*3/3
24x/24=120/24 simplify: 10x =2 
simplified =5 divide both sides by 10: 10x/10=10/2
x=5 simplified = 1/5 
 x=1/5
