Question

HELP ! :/
Solve the solution using Substitution. Check Your Answer.

y = -2x + 8
5y - x + 4 = 0

(Answer must be ordered pair)

Answer 1

have you tried putting in the equation solved for y into the other equation?

Answer 2

like so:
5(-2x+8)-x+4=0
now solve for x

Answer 3

Ohhhh okay! Give me a moment....

Answer 4

x = 34? @freckles

Answer 5

so you distribute:
-10x+40-x+4=0
combined like terms
-11x+44=0 <--- hmmm so looking at this I think you should try again

Answer 6

So, I'm still looking for X correct?

Answer 7

yep

Answer 8

you might want to look at the equation you "solved" to get x=34
because I do not believe that is correct.
I actually showed you to distribute and then combine like terms above.
You are actually one step away from solving for x since I have done most of the work for you.

Answer 9

-11x+44=0
so x=?

Answer 10

4??

Answer 11

sounds good

Answer 12

now do you know how to find y?

Answer 13

y = -2x + 8
you have x is 4
so replace x with 4
this gives you enough info to find y

Answer 14

So -2x(4) + 8?

Answer 15

yep

Answer 16

where x means multiply right?

Answer 17

Right @freckles
