Solve the given system of equations using the Substitution method. Solution: Step 1: write the above equation and give the name eq (i) & eq (ii). x + 2y = -3------> (i) x - 3y = 2--------> (ii) Step 2: Solve the eq (i) for “ x ”. x + 2y = -3. x = -3 - 2y. Step 3: Substitute the above value in eq (ii) and Simplify for “ y ”. (-3 - 2y) –3 y = 2.
