Question

solve using the elimination method plz help!!!
5x+3y=-11
7x-2y=19

Answer 1

Multiply the first equation by 2 and the second equation by 3. Then your y term will be eliminated and you can solve for x. Once you have x, you can plug that value back into either quation and solve for y.

Answer 2

i get stuck when i get to 5(31/16)+3y=-11

Answer 3

because i get that x=31/16

Answer 4

2(5x + 3y = -11)
3(7x - 2y = 19)

10x + 6y = -22
21x - 6y = 57

31x = 35
x = 35/31

Answer 5

so when i plug it back in it doesnt make sence to me how to solve

Answer 6

ohhh

Answer 7

i was messing up with the mulitplicaiton!!!

Answer 8

5(35/31) + 3y = -11
175/31 + 3y = -11
3y =31(-11) - 175
------- ----
31 31

3y = 341 - 175
--------
3

3y = 166
----
3

y = 166 1
--- x ---
3 3

y = 166/9

Answer 9

but it says the answer is (35/31,-172/31)

Answer 10

yup y=-172/31
.. just a little typing error in the above solution.

Answer 11

OOPS.. I'm sorry

Answer 12

3y = 31(-11) - 175
------ ----
31 31

3y = -341 - 175
---------
31

3y = -516
----
31

3y = -516 1
---- x --
31 3

y = -516
----
93

y = -172
-----
31
