Solve each system using substitution x=-2y=1 x=y-5

You solve either one for y, but I chose the second one.

Add 5 to both sides and you get

X+5=y

Plug this in to the first equation

X=-2 (x+5) + 1

I am assuming that is plus one instead of equal since the keys are near each other on a phone.

Back to the math: use the distributive property to get

X=-2x-10+1 now combine terms

X=-2x-9

Add 2x to both sides to get

3x=9

Divide both sides by 3 to get

X=3

Now plug 3 in as x in any of the above

I will choose the second one again

So 3=y-5 subtract 5 from both sides to get

Y=8

So the solution is (3,8)
