Question

graph x + y = 6 and x -y = 4 on the same axes. Give the coordinates of the point where the lines intersect.

Answer 1

5 1

Answer 2

what is this

Answer 3

x + y = 6
x - y = 4
__________
2x = 10
x = 5
y = 1

Therefore the point is (5,1)

Answer 4

You can add the equations together to eliminate y, so that you can easily solve for x. Once you do that, finding the value of y is obvious.

Answer 5
