Set up equation: Set up the equation from the given problem.We are given the equation (x+6)/(x−5)=4/3. We need to solve for x.
Cross-multiply: Cross-multiply to eliminate the fractions.Cross-multiplying gives us 3(x+6)=4(x−5).
Distribute numbers: Distribute the numbers on both sides of the equation.3(x)+3(6)=4(x)−4(5)This simplifies to 3x+18=4x−20.
Move terms: Move the variable terms to one side and the constant terms to the other side.Subtract 3x from both sides to get the x terms on one side:3x+18−3x=4x−20−3xThis simplifies to 18=x−20.
Isolate x: Isolate x by adding 20 to both sides of the equation.18+20=x−20+20This simplifies to 38=x.
