7x-5\left(2\times 7+4\right)=63
Multiply both sides of the equation by 7.
7x-5\left(14+4\right)=63
Multiply 2 and 7 to get 14.
7x-5\times 18=63
Add 14 and 4 to get 18.
7x-90=63
Multiply 5 and 18 to get 90.
7x=63+90
Add 90 to both sides.
7x=153
Add 63 and 90 to get 153.
x=\frac{153}{7}
Divide both sides by 7.
