The graphs of the straight lines with equations y=2x−2y = 2x - 2y=2x−2 and x+y=4x + y = 4x+y=4 have been drawn on the grid.

A coordinate grid with x and y axes ranging from -2 to 6. Two straight lines are plotted. The first line, y = 2x - 2, passes through the points (0, -2), (1, 0), (2, 2), and (3, 4). The second line, x + y = 4, passes through the points (0, 4), (2, 2), and (4, 0). The two lines intersect at the point (2, 2).

Use the graphs to solve the simultaneous equations

y=2x−2 y = 2x - 2 y=2x−2 x+y=4 x + y = 4 x+y=4
