Plug in a made up value for one of the variables to figure out what the other would be to make the equation valid. For example, if you set y to equal 1, then x has to equal 1, because 1 minus 2 equals 1.

if y equaled 2, x would have to equal 5 to satisfy the equations parameters, and those x and y values you achieve are your coordinates.

rewrite the first to x = 1+2y and inset in the second 2(1+2y)y=4 and solve 2+4yy = 4 2+3y=4 3y = 4+2 y = 6/2 y=3 x = 1+2y x=1+2*3 x = 5

rewrite the first to x = 1+2y and inset in the second 2(1+2y)y=4 and solve 2+4yy = 4 2+3y=4 3y = 4+2 y = 6/3 y=2 x = 1+2y x=1+2*2 x = 3

x2y=1 /2 2xy=4 2x4y=2 2xy=4   3y=6 y=6/3= 2 than y=2  2x2=4  2x=6  x=6/2 =3 x=3 y=2
