Answer 1

Answer:

Third answer shown

Step-by-step explanation:

Since each equation has a right side equal to the same thing, y, those right sides must be equal to each other.

                                                    x + 3 = -2x + 6

Add 2x to both sides.                2x          2x

                                                   3x + 3 =  0 + 6

                                                   3x + 3 = 6

Subtract 3 on both sides.                -3     -3

                                                      3x    =    3

Divide both sides by 3.                   x = 1

Now, let's see what y must be if x equals 1.

Line M:  y = x + 3 -->  y = 1 + 3 --> y = 4

Line N: y = -2x +6 --> y = -2(1) +6 --> y = -2 + 6 --> y = 4, confirmed

So the ordered pair (x, y) that satisfies both equations is (1, 4)

*** This means that if you graphed both lines on an xy-coordinate plane, the point (1,4) would be the point where the two lines intersect.

That is the third answer shown.
