4x+28x=20+7x
Multiply both sides of the equation by 28, the least common multiple of 7,4.
32x=20+7x
Combine 4x and 28x to get 32x.
32x-7x=20
Subtract 7x from both sides.
25x=20
Combine 32x and -7x to get 25x.
x=\frac{20}{25}
Divide both sides by 25.
x=\frac{4}{5}
Reduce the fraction \frac{20}{25} to lowest terms by extracting and canceling out 5.
