^^^^^^^^^^^^^^^^^^^

Well, I really need help. @IMANINJA127

OpenStudy (igreen):

Here, we can use substitution.. We can substitute 3y + 5 for 'x' in the 2nd equation: x - 4y = 3 3y + 5 - 4y = 3 Combine like terms: -y + 5 = 3 Subtract 5 to both sides, what's 3 - 5?

OpenStudy (anonymous):

-2

OpenStudy (igreen):

Yes, so we have: -y = -2 Now divide -1 to both sides, what's -2 / -1?

OpenStudy (anonymous):

um.. positive one?

OpenStudy (anonymous):

Lol or not

OpenStudy (igreen):

No..check again.

OpenStudy (anonymous):

Two...

OpenStudy (igreen):

Yes, so the y-value of our solution is 2. Now we plug this back into any of the two equations to find the x-value. x = 3y + 5 x = 3(2) + 5 What's 3 * 2?

OpenStudy (anonymous):

6

OpenStudy (igreen):

Yes, that gives us: x = 6 + 5 What's 6 + 5?

OpenStudy (anonymous):

11

OpenStudy (igreen):

Yep, so the x-value of our solution is 11. So our full answer is (11, 2).

OpenStudy (anonymous):

Thanks, can you help me with some more?
