Because x - 3 is in the denominator, and the denominator cannot equal 0, x - 3 $\ne$ 0. x $\ne$ 3 Because x - 6 is in the denominator, and the denominator cannot equal 0, x - 6 $\ne$ 0. x $\ne$ 6 To solve this equation, we equate the cross products. 5 $\times$ (x - 6) = 10 $\times$ (x - 3) Use the distributive property. 5x - 30 = 10x - 30 Subtract 5x from both sides. -30 = 5x - 30 Add 30 to both sides. 0 = 5x Divide both sides by 5 x = 0
