Solving systems of equations algebraically

Front

Solve for x and y
2x − 3y = −1
 y = x − 1

Back

(4,3)

Front

Solve for x and y.
y = 2/3x - 2
y = -x + 3

Back

(3,0)

Front

Solve for x and y
3x + 2y = 16
7x + y = 19

Back

(2,5)

Front

Solve for x and y
5x + 3y = 7
y = 4

Back

(-1,4)

Front

Solve:
y = 2x -11
-3y = -6x -15

Back

No solution (parallel lines)

Front

Is (3,-4) a solution to this system?

Back

no

Front

Pick the ordered pair that is NOT a solution: (0,0), (1,-1), (2,0), (4,-4)

Back

(0,0)

Front

For the inequality: y > 3x - 5, would you shade (0,0) or shade the other side?

Back

shade (0,0) -- it is a solution

Front

4x+8y=20
-4x+2y=-30

Back

(7,-1)

Front

Solve the system of equations: x-y=11 and 2x+y=19

Back

(10,-1)
