x + y = -4

x - y = 2

solve for x in the second equation.

x= y+2

Put that in for x in the first equation:

x+y=-4

(y+2) + y = -4

solve for y. Then, x= y+2

i don't get it.How did you get that?What does x equal?

re read my post. I tell you how I got it. you will have then to solve for x, then, put that value of x back in the equation, and solve for y. Post your work.

does x =5?

i have been trying to

figure out how to solve this

problem but i just can't.

it seems so difficult.

i have already seen some

examples but i still don't

understand!!

SOLVE USING THE SUBSTITUTION METHOD.

EX. x+y=4

y=2x+1

please help in the easiest way.

thanks a lot!

teach me how to do this

x=2y+7

x=y+4

- Substitution Method-Plz help -
**Anonymous**, Friday, March 8, 2013 at 8:04amTo solve the system given below using substitution, it is best to start by solving the first equation for y.

11x + y = 12

9y + 3x = 7

can you please explain please :)
