\frac{1}{7}x+\frac{1}{7}\times 14=\frac{1}{4}\left(x+20\right)
Use the distributive property to multiply \frac{1}{7} by x+14.
\frac{1}{7}x+\frac{14}{7}=\frac{1}{4}\left(x+20\right)
Multiply \frac{1}{7} and 14 to get \frac{14}{7}.
\frac{1}{7}x+2=\frac{1}{4}\left(x+20\right)
Divide 14 by 7 to get 2.
\frac{1}{7}x+2=\frac{1}{4}x+\frac{1}{4}\times 20
Use the distributive property to multiply \frac{1}{4} by x+20.
\frac{1}{7}x+2=\frac{1}{4}x+\frac{20}{4}
Multiply \frac{1}{4} and 20 to get \frac{20}{4}.
\frac{1}{7}x+2=\frac{1}{4}x+5
Divide 20 by 4 to get 5.
\frac{1}{7}x+2-\frac{1}{4}x=5
Subtract \frac{1}{4}x from both sides.
-\frac{3}{28}x+2=5
Combine \frac{1}{7}x and -\frac{1}{4}x to get -\frac{3}{28}x.
-\frac{3}{28}x=5-2
Subtract 2 from both sides.
-\frac{3}{28}x=3
Subtract 2 from 5 to get 3.
x=3\left(-\frac{28}{3}\right)
Multiply both sides by -\frac{28}{3}, the reciprocal of -\frac{3}{28}.
x=-28
Cancel out 3 and 3.
