You can substitute the value of y(5/6 x + 1) from the first equation for y in the second and get [tex]-x + ( \frac{5}{6} x+1) = 2
[/tex] which becomes [tex]- \frac{1}{6} x + 1 -1=2-1
[/tex] and you get
y = 5/6x + 1
so we sub in 5/6x + 1 in for y in the other equation
-x + y = 2
-x + 5/6x + 1 = 2
-x + 5/6x = 2 - 1
-6/6x + 5/6x = 1
-1/6x = 1
x = 1 * -6
x = -6
-x + y = 2
-(-6) + y = 2
6 + y = 2
y = 2 - 6
y = -4
solution is (-6,-4)
