30+3v=2v
Variable v cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 30v, the least common multiple of v,-10,15.
30+3v-2v=0
Subtract 2v from both sides.
30+v=0
Combine 3v and -2v to get v.
v=-30
Subtract 30 from both sides. Anything subtracted from zero gives its negation.
