7\left(7\times 3+3\right)x=18
Multiply both sides of the equation by 21, the least common multiple of 3,7.
7\left(21+3\right)x=18
Multiply 7 and 3 to get 21.
7\times 24x=18
Add 21 and 3 to get 24.
168x=18
Multiply 7 and 24 to get 168.
x=\frac{18}{168}
Divide both sides by 168.
x=\frac{3}{28}
Reduce the fraction \frac{18}{168} to lowest terms by extracting and canceling out 6.
