Solving m=y5x4m = \frac{y-5}{x-4} for yy

To solve the formula m=y5x4m = \frac{y-5}{x-4} for yy: 1. Note restriction: xeq4x eq 4. 2. Clear fractions: Multiply by (x4)(x-4) to get m(x4)=y5m(x-4) = y-5. 3. Simplify: mx4m=y5mx - 4m = y - 5. 4. Isolate yy: Add 55 to both sides to obtain y=mx4m+5y = mx - 4m + 5. This problem provides additional practice in isolating variables within rational formulas.
