5\left(3v+4\right)=4\left(4v-6\right)
Multiply both sides of the equation by 20, the least common multiple of 4,5.
15v+20=4\left(4v-6\right)
Use the distributive property to multiply 5 by 3v+4.
15v+20=16v-24
Use the distributive property to multiply 4 by 4v-6.
15v+20-16v=-24
Subtract 16v from both sides.
-v+20=-24
Combine 15v and -16v to get -v.
-v=-24-20
Subtract 20 from both sides.
-v=-44
Subtract 20 from -24 to get -44.
v=44
Multiply both sides by -1.
