Answer:
(-2, -9) or x=-2, y=-9
Step-by-step explanation:
First, isolate x in one of the equations.
y = 4x-1
y+1 = 4x
(y+1)/4 = x
Next, substitute in (y+1)/4 for x in the second equation.
y = 2x-5
y = 2[(y+1)/4]-5
y = (y+1)/2 - 5
At this point, break up your fraction so you can isolate y.
y = (y+1)/2 - 5
y = y/2 + 1/2 -5
y - y/2 = 1/2 - 5
y/2 = -9/2
y=-9
Finally, substitute -9 for y in either equation to find x.
y = 4x-1
-9 = 4x-1
-8 = 4x
x=-2
Your answer is (-2, -9) or x=-2, y=-9
