6j – Systems of Equations – Mixed Review
Solve the following systems algebraically. Decide whether to use substitution or elimination. But you
cannot
do only one method for the entire worksheet!!! Graph the system and confirm results.
1. 2x + 3y = 2
2. 5x+2y = 11
3. y = 2x - 1
4x - 9y = -1 x + y = 4 y = 3x - 5
4. x - y = -11
5. 6x - 7y = 47
7x + 4y = -22
2x + 5y = -21
Complete the sentence!
6. Two lines intersect zero, _________, or infinite times. The systems that contain these lines are
referred to as inconsistent (formed by parallel lines), independent (lines intersecting), or dependent (lines
that are the same).
