Select a response, navigate to the desired position and insert response at that position. Responses can be selected and inserted using the space bar, enter key, left mouse button or touchpad. Responses can be moved using the up and down arrow keys or by dragging with a mouse.y=−4−7(2y+11)−2y=−13−16y=64(3,−4)x−2y=11→ x=2y+11−16y−77=−13−14y−77−2y=−13

Answer 1

−7x - 2y = -13
x - 2y = 11
x = 2y + 11
−7(2y + 11) - 2y = -13
-14y - 77 - 2y = -13
-16y - 77 = -13
-16y = 64
y = -4
x = 2(-4) + 11
x = 3
The solution is (3, -4)
