Solve the system by elimination.
3x + y = 19
2x - y = 6
(5, 14)
(4, 5)
(5, 4)
(14, 5)
Solve the system by elimination. Hint: What will you use as a multiplier and on which equation?
x + 6y = 17
x - 3y = 8
(5, 2)
(11, 1)
(1, 11)
no solution
What would be the first step in finding the solution using elimination?
2x + 2y = -2
3x - 2y = 12
you cannot solve this using elimination
cross out the 2x and 3x
Add the like terms. The y terms will zero out.
change to slope intercept form and graph
Solve the system. You could use elimination OR substitution.
4x + 5y = 5
x = -10y + 3
( 1 , 5 )
( 0.2 , 1 )
No Solution
( 1 , 1/5 )
What is the variable that willl be "eliminated"?

5x + 4y = -14
x variable
y variables
both variables
