Question

Which ordered pair is the best estimate for the

solution of the system of equations?
y =
3x + 6
y = 1x – 2

Answer 1

-4, -6

Explanation:

3x+6= 1x-2

2x+6= -2

2x= -8

x= -4

Now that you have your x variable, you can go back and plug it in to your original equations:

y= 3(-4)+6,

y= (-12)+6 therefore y= -6

y=1(-4) -2,

y= (-4) -2 therefore y = -6
