Question

Solve each system of equations by substitution. List the ordered pair.

Answer 1

y=6x-11
-2x-3y=-7
-2x-3(6x-11)=-7
-2x-18x+66=-7
-20x=-73
x=3.65
y=6(3.65)-11=10.9

y=-3x+5
5x-4y=-3
5x-4(-3x+5)=-3
5x+12x=17
x=1
y=-3(1)+5=2

2x-3y=-1
y=x-1
2x-3(x-1)=-1
-x=-4
x=4
y=4-1=3

-3x-3y=3
y=-5x-17
-3x-3(-5x-17)=3
12x=-48
x=-4
y=-5(-4)-17=3
