28x-14x=7\times 4+4+84
Multiply both sides of the equation by 28, the least common multiple of 2,4,7.
14x=7\times 4+4+84
Combine 28x and -14x to get 14x.
14x=28+4+84
Multiply 7 and 4 to get 28.
14x=32+84
Add 28 and 4 to get 32.
14x=116
Add 32 and 84 to get 116.
x=\frac{116}{14}
Divide both sides by 14.
x=\frac{58}{7}
Reduce the fraction \frac{116}{14} to lowest terms by extracting and canceling out 2.
