x\times 4-10=9x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
x\times 4-10-9x=0
Subtract 9x from both sides.
-5x-10=0
Combine x\times 4 and -9x to get -5x.
-5x=10
Add 10 to both sides. Anything plus zero gives itself.
x=\frac{10}{-5}
Divide both sides by -5.
x=-2
Divide 10 by -5 to get -2.
