Y=-6X-5 Y=-2X-1

Question

SOLVE SYSTEMS BY SUBSTITUTION

Answer 1

Since both are in the for y=, substitution results in setting the 2 equations equal to each other

-6x-5=-2x-1 Add 6x to both sides

-6x-5+6x=-2x-1+6x Simplify

-5=-1+4x Add 1 to both sides

-5+1=-1+4x+1 Simplify

-4=4x Divide both sides by 4

-4/4=4x/4 Simplify

x=-1

Not plug this into either of the original equations to solve for y

y=-2(-1)-2

y=2-1

y=1

Solution is (-1,1)
