The Substitution Method

Solve the linear system using the substitution method.
3x + 4y = -4 |
Equation 1 |
Step 1: Solve Equation 2 for x. |
Step 2: Substitute the expression for x into Equation 1 and solve for y. |
Step 3: Substitute the value of y into revised Equasion 2 and solve for x. |
x + 2y = 2 |
3x + 4y = -4 |
x = -2y + 2 |
The solution is (-8,5).
