\left(x+10\right)\times 21=56\times 9
Variable x cannot be equal to -10 since division by zero is not defined. Multiply both sides of the equation by 56\left(x+10\right), the least common multiple of 56,x+10.
21x+210=56\times 9
Use the distributive property to multiply x+10 by 21.
21x+210=504
Multiply 56 and 9 to get 504.
21x=504-210
Subtract 210 from both sides.
21x=294
Subtract 210 from 504 to get 294.
x=\frac{294}{21}
Divide both sides by 21.
x=14
Divide 294 by 21 to get 14.
