Question

5x-7y=-11
6x+7y=33 If anyone could answer that would be great! THANK YOU

Answer 1

Answer:

First add together to get rid of y

11x=22

x=2

then plug it in

6(2)+7y=33

10+7y=33

7y=23

y=23/7

solution

(2,23/7)

Hope This Helps!!!

Answer 2

Answer:

x = 2

y = 3

Step-by-step explanation:

if you add the equations together you get:

11x = 22

x = 2

substitute '2 in for x' to get value of 'y':

5(2) - 7y = -11

10 - 7y = -11

-7y = -21

y = 3

Check:

6(2) + 7(3) should equal 33

12 + 21 = 33

33 = 33
