Question

can some help me with,
Substitution Method:
4x + y = 11
x + 2y = 8
A:
(3, 2)

(2, 3)

(-2, -3)

(-2, 3)

Answer 1

I don't know which variable substitute first.

Answer 2

If I were you I would subsitute the second equation into the first. So it would start by solving 4(8-2y) + y = 11, then you would solve for y. *I started by getting X by itself in the second equation*

Answer 3

Hmm..maybe not, it didn't work out as planned. Have you tried just filling in all the options into both equations? I elimnated all of them out except for B (2,3) by filling in the numbers..

Answer 4

Yep that's right thank you!

Answer 5

Math makes me feel so dumb sometimes.

Answer 6

Lol I know the feeling, and it doesn't get any better the more classes you take. I'm in College algebra/Algebra 2 and chemistry and I can't remember how multiply radicals sometimes

Answer 7

I haven't even gotten into radicals yet. That's At the end of the year for 9th graders.
