I have to put numbers in the x and y to get them to equal 2 for the first prob and 9 on the second prob thanks
I should have put in a + sign for and sorry
igggghhht so you got:
5x + 3y = 2
6x + 4y = 9
well one thing you can do is to get rid of one coefficient, let's say the y one.
mutliply the first equation by 4, and the second one by 3, then substract them:
20x + 12y = 8
18x + 12y = 27
2x = -19
x = -19/2
plug that in ant of the initial equations to find y
I understand what you did here..thank you very much. My student is saying thank you also. How do you do it for Y? Plug in the X answer for Y and solve?
exactly, you can plug it in the first or second initial equation and it should give you the same answer
we get 190 =8 ..does that make sense?
23.75 = y ..does that sound right?
we get two different answers, 23.75 and 171
oops she got 23.75 for first equation and 6.3 for the second equation
ok well if we have x = -19/2:
5x + 3y =2
-95/2 + 3y = 2
y = (2 + 95/2)/3 = 16.5
6x + 4y = 9
-57 + 4y = 9
4y = 66
y = 66/4 = 16.5
You are really good. Mariah says thanks and what about 2x +5y =16 and 4x +7y=23
