Solve the following linear system of equations using substitution.
Y=3x-5
Y=2x-6
2 answers:
3x-5=2x-6
Move 2x to the same side as 3x.
3x-2x = x
X-5=-6
add 5 to the -6.
X = 5-6
X=-1
Y=3x-5
y=2x-6
Move the X's to the other side on both equations to make equations easier to solve.
-3x+y=-5
-2x+y=-6
Subtract equations.
-x=1
x=-1
y=3x-5
y=3(-1) -5
y=-3-5
y=-8
