45+15x=20\times 3x
Use the distributive property to multiply 15 by 3+x.
45+15x=60x
Multiply 20 and 3 to get 60.
45+15x-60x=0
Subtract 60x from both sides.
45-45x=0
Combine 15x and -60x to get -45x.
-45x=-45
Subtract 45 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-45}{-45}
Divide both sides by -45.
x=1
Divide -45 by -45 to get 1.
