9\times 2+9x\times 4=3\times 7+9x\times \frac{37}{9}
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 9x, the least common multiple of x,3x,9.
18+9x\times 4=3\times 7+9x\times \frac{37}{9}
Multiply 9 and 2 to get 18.
18+36x=3\times 7+9x\times \frac{37}{9}
Multiply 9 and 4 to get 36.
18+36x=21+9x\times \frac{37}{9}
Multiply 3 and 7 to get 21.
18+36x=21+37x
Multiply 9 and \frac{37}{9} to get 37.
18+36x-37x=21
Subtract 37x from both sides.
18-x=21
Combine 36x and -37x to get -x.
-x=21-18
Subtract 18 from both sides.
-x=3
Subtract 18 from 21 to get 3.
x=-3
Multiply both sides by -1.
