-x + 2y = -4
-x = -2y - 4
x = 2y + 4
5(2y + 4) - 4y = 8
10y + 20 - 4y = 8
6y + 20 = 8
6y = -18
y = -3
-x + 2y = -4
-x + 2(-3) = -4
-x - 6 = -4
-x = 2
x = -2
The coordinate pair is (-2, -3) (x = -2, y = -3.)

Answer:
None
Step-by-step explanation:
The information is already enough to prove that the triangles are congruent.
From second equation y = 8 - x so
7x + 2(8 - x) = -14
5x = -14 - 16 = -30
x = -6
and y = 8 - -6 = 14
Answer x=-6,y=14
Answer:
x = 20
Step-by-step explanation:
7x - 99= 2x + 1
7x - 2x = 1 + 99
5x = 100
x = 20
