Solve Systems Ordered Pair

Will the solution (-3, -7) make the following system of equations a true statement? 
y = 4x + 5
y = x – 4

• YES

• NO

Solve by elimination:
4x+9y=28
-4x-y=-28

• (-7,0)

• (6,0)

• (-6,0)

• (7,0)

Solve by elimination
-12x-10y= 0
6x+5y= -1

• infinite solutions

• (0,0)

• no solution

• (2,1)

Write the solution to this system of equations as a coordinate pair (x,y) with no spaces.

3x + y = 10

-x - y = -20

Write the solution to this system of equations using a coordinate pair, (x,y), with no spaces.

y = -4x

-2x + y = -6

What is the solution?

• No solution

• (0, 2)

• (0, -4)

• (3, -3)

What variable do you eliminate?

4x + 8y = 20

−4x + 2y = −30

• X because they have opposite signs

• Y because they have opposite signs

Solve the following system of equations.

x+y=-5

x-2y=7

• (-7,2)

• (3,-2)

• (-1,-4)

• No Solution
