30x+0\times 5-x=0\times 51
Multiply both sides of the equation by 2.
30x+0-x=0\times 51
Multiply 0 and 5 to get 0.
29x+0=0\times 51
Combine 30x and -x to get 29x.
29x=0\times 51
Anything plus zero gives itself.
29x=0
Multiply 0 and 51 to get 0.
x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since 29 is not equal to 0, x must be equal to 0.
