y=%28-1%2F4%29x%2B3 Use this to substitute for y.
-2x%2By=-6 Substitute for y from above.
-2x%2B%28-1%2F4%29x%2B3=-6 Subtract 3 from each side.
%28-9%2F4%29x=-9 Multiply each side by -4/9
x=4 ANSWER 1: x=4
y=%28-1%2F4%29x%2B3
y=%28-1%2F4%29%284%29%2B3
y=-1%2B3
y=2 ANSWER 2: y=2
CHECK:
-2x%2By=-6
-2%284%29%2B2=-6
-8%2B2=-6
-6=-6
