Line up equations so x is over x and y is over y
Multiply the equations to make the coefficients of x or y opposite of each other
Add the two equations (one variable should be eliminated)
Solve for the remaining variable
st
Plug the answer into 1 equation
Write the answer as an ordered pair (x, y)
nd
Check solution with 2 equation
1) ____________
2) ____________
3x + 4y = 22
-y = -2x + 6
x – 5y = -37
5y = -3x + 22
3) ____________
4) ____________
2x + 3y = 2
6x + 3y = 6
3x – 4y = -14
8x + 5y = 12
5) ____________
6) ____________
4x = -3y + 27
y = -2x + 1
3x = 4y + 29
3x – y = 14
