Question

Please, please, please help!!! I will fan and medal!!!!
Solve the system of inequalities by using the substitution method. Show work.
y <= x - 2
x + 3y >= 6

Answer 1

There are many solutions to this..do you have choices?

Answer 2

No... I'm supposed to use the substitution method?

Answer 3

Yeah, substitute y in the first equation to the one in the second.

x + 3y ≥ 6
x + 3(x - 2) ≥ 6
x + 3x - 6 ≥ 6
4x - 6 ≥ 6
4x ≥ 12
x ≥ 3

Answer 4

Did you see what I did there?

Answer 5

... To be honest, no. I don't get any of it.

Answer 6

Well I substituted y <= x - 2 into x + 3y >= 6. I substitute it by putting (x - 2) in for 'y' in x + 3y >= 6.

Answer 7

Wow your smart lol. Thank you so much!!!!

Answer 8

Thanks :) No problem.
