Systems Quiz 2

The first step in using the Elimination Method to solve a system of equations is to

• get both equations in slope-intercept form.

• look for a zero pair.

• get the x term or y term isolated.

• identify the m and the b of the equation.

Solve the system using Elimination.

-4x - 2y = -12

4x + 8y = -24

• (5, 6)

• (4, -3)

• (6, -6)

• (6, -2)

Use Elimination to solve.

-3x + 3y = -33

6x - 3y = 57

• (-3, 8)

• (8, -3)

• (10, -1)

• (10, 1)

To eliminate a variable in the system, should you add the equations or subtract the equations?

• Add

• Subtract

• Neither

Which variable would be easiest to eliminate?

• x

• y

• Neither

Solve by elimination:

7x+y=-9

-3x-y=5

• No solution

• (-1,8)

• (-2,-3)

• (-1,-2)
