20x=30\left(x-0\times 4\right)
Multiply 0 and 0 to get 0.
20x=30\left(x-0\right)
Multiply 0 and 4 to get 0.
20x-30\left(x-0\right)=0
Subtract 30\left(x-0\right) from both sides.
20x-30x=0
Reorder the terms.
-10x=0
Combine 20x and -30x to get -10x.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since -10 is not equal to 0, x must be equal to 0.
