0=4x+16\times 3+2
Multiply both sides of the equation by 3.
0=4x+48+2
Multiply 16 and 3 to get 48.
0=4x+50
Add 48 and 2 to get 50.
4x+50=0
Swap sides so that all variable terms are on the left hand side.
4x=-50
Subtract 50 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-50}{4}
Divide both sides by 4.
x=-\frac{25}{2}
Reduce the fraction \frac{-50}{4} to lowest terms by extracting and canceling out 2.
