50+2\times 15=5x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 2x, the least common multiple of 2x,x.
50+30=5x
Multiply 2 and 15 to get 30.
80=5x
Add 50 and 30 to get 80.
5x=80
Swap sides so that all variable terms are on the left hand side.
x=\frac{80}{5}
Divide both sides by 5.
x=16
Divide 80 by 5 to get 16.
