You can  put this solution on YOUR website! Given 3X/4-5=2X/3
 
Clear the denominators by multiplying everything by 12 to get 
12x - 60 = 8x
 
Simplifying 
12X + -60 = 8X
 
Reorder the terms: 
-60 + 12X = 8X
 
Solving 
-60 + 12X = 8X
 
Solving for variable 'X'.
 
Move all terms containing X to the left, all other terms to the right.
 
Add '-8X' to each side of the equation. 
-60 + 12X + -8X = 8X + -8X
 
Combine like terms: 12X + -8X = 4X 
-60 + 4X = 8X + -8X
 
Combine like terms: 8X + -8X = 0 
-60 + 4X = 0
 
Add '60' to each side of the equation. 
-60 + 60 + 4X = 0 + 60
 
Combine like terms: -60 + 60 = 0 
0 + 4X = 0 + 60 
4X = 0 + 60
 
Combine like terms: 0 + 60 = 60 
4X = 60
 
Divide each side by '4'. 
X = 15
 
Simplifying 
X = 15
