Question: 2. Substitution method Steps (1) Solve one equation for a variable, say y. (2) Substitute the expression obtained for y for all occurrences of y

2. Substitution method Steps (1) Solve one equation for a variable, say y. (2) Substitute the expression obtained for y for all occurrences of y in the other equation. (3) Solve the resulting equation. (4) Substitute the solution found in step (3) in the equation found in step (1) Examples (1) 3x - 2y = -3 3x +y= -9 (2) + 3y = -1 2x + y = 2 (3) 6x - 3y = 9 2x -y=3 (4) 3x + 2y = 0 2gr - 3y = -13
