3\times 5x=7\left(2x-4\right)
Multiply both sides of the equation by 21, the least common multiple of 7,3.
15x=7\left(2x-4\right)
Multiply 3 and 5 to get 15.
15x=14x-28
Use the distributive property to multiply 7 by 2x-4.
15x-14x=-28
Subtract 14x from both sides.
x=-28
Combine 15x and -14x to get x.
