Example 2: Solve by substitution $$ \begin{aligned} 2x + 5y &= 12 \\ 4x - y &= 2 \end{aligned} $$ Solution: Step 1: Solve one of the equations for either x = or y =. Since the coefficient of y in

Solve the following equations by substitution method y = −3x + 5 and 5x − 4y = −3. Solution : y = −3x + 5 -----(1) 5x − 4y = −3 -----(2) Substitute y = -3x + 5 in the second equation. 5x - 4 (-3x + 5) =
