6x\times \frac{5}{3}+3\times 3=x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 6x, the least common multiple of 3,2x,6.
10x+3\times 3=x
Multiply 6 and \frac{5}{3} to get 10.
10x+9=x
Multiply 3 and 3 to get 9.
10x+9-x=0
Subtract x from both sides.
9x+9=0
Combine 10x and -x to get 9x.
9x=-9
Subtract 9 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-9}{9}
Divide both sides by 9.
x=-1
Divide -9 by 9 to get -1.
