Steps for Solving Linear Equation

Variable x cannot be equal to any of the values 2,4,6,8 since division by zero is not defined. Multiply both sides of the equation by \left(x-8\right)\left(x-6\right)\left(x-4\right)\left(x-2\right), the least common multiple of x-2,x-8,x-4,x-6.

$$\left(x-8\right)\left(x-6\right)\left(x-4\right)\left(x-1\right)+\left(x-6\right)\left(x-4\right)\left(x-2\right)\left(x-7\right)=\left(x-8\right)\left(x-6\right)\left(x-2\right)\left(x-3\right)+\left(x-8\right)\left(x-4\right)\left(x-2\right)\left(x-5\right)$$

Subtract 528 from 608 to get 80.

$$16x=80$$

Divide both sides by 16.

$$x=\frac{80}{16}$$

Divide 80 by 16 to get 5.

$$x=5$$
