You can put this solution on YOUR website! 1. The least common denominator of all three fractions is 12, so we can multiply the entire equation by 12 (*NOTE: You can ONLY do this with equations; do not try this with expressions*):
If you have trouble with this step, a surefire way to get a common denominator (although not necessarily the least common denominator) is to multiply the denominators of all the fractions in the equation, omitting duplicates. In this case it would be the least common denominator: 3 * 4 (the second 3 is omitted) = 12

2. Simplify:
Simplify the numerators:
Simplify each fraction by dividing the numerator by the denominator: 28 - 4x = 3x
Add 4x to both sides: 28 = 7x
Divide both sides by 7 to get x by itself: 4 = x
***
3. Therefore, your solution is x = 4.
Hope I helped! Good luck! =)
