Solving Systems of Equations

Solve the system of equations using elimination: $2x + 3y = 13$
$4x - 3y = 3$

Use substitution to solve the system of equations: $3x + y = 9$
$x - y = 1$

The system of equations has a solution at the point where the lines intersect:
$y = x + 2$
$y = -x + 4$

What is the solution to the system of equations using elimination?
$3x + 4y = 15$
$6x + 8y = 30$

Find the solution to the system of equations using elimination:
$5x + 2y = 7$
$3x - 2y = 1$
