hero (hero):

Hint: Set y = y

OpenStudy (anonymous):

OpenStudy (anonymous):

im confused:/

hero (hero):

Do: x + 4 = 2x + 5

OpenStudy (anonymous):

Okay. Ill solve that right now

hero (hero):

When you find x value, plug it into one of the original equations to find y value

OpenStudy (anonymous):

I got x=1

OpenStudy (anonymous):

Okay, Thank you.

OpenStudy (anonymous):

Ill do that now

hero (hero):

Actually, x = 1 is not correct, but it is close.

OpenStudy (anonymous):

is it 2?

OpenStudy (anonymous):

x = -1

OpenStudy (anonymous):

and y = 3

OpenStudy (anonymous):

oh right i forgot to add negative sign.

OpenStudy (anonymous):

So when you put them together, they both equal 3 now. Thanks a million for explaining this.
