Question

Solve the system of equations by any method you choose
-4x-2y=-2
-9x+3y=3

Answer 1

(0, 1)

Explanation:

You can solve this by using the substitution or elimination method. For this problem, I'm going to use the substitution method. First, rewrite -4x-2y=-2 in slope-intercept form, which would be y=-2x+1. Substitute the y value in -9x+3y=3 (which would be -9x+3(-2x+1)=3) and solve.

-9x+3(-2x+1)=3

-9x-6x+3=3

-15x=0

x=0

Now, substitute the x value in for the x in any equation. You can do -4(0)-2y=-2 or -9(0)+3y=3. I'm going to use -9(0)+3y=3.

-9(0)+3y=3

3y=3

y=1

Answer 2

Answer:1. Use substitution to solve the system of equations:

-x + 2y=7

x - 3y = 3

2. Solve the system of equations by the elimination method

a. 2x+ y = -17

x - y = 2

b. 3x + y = -15

x + 2y = -10
