I am confused about this equation; 5x+2y=6, 7x+8y=-2 Does anyone think they can help me out?

I cannot solve it step-by-step because like I'm helping other people cuz I'm busy with my homework so just I'm going to direct you the question you're supposed to solve simultaneous equation by any method example elimination method substitution method then you get the answer if you get stuck you can inform me

(2,-2)

Step-by-step explanation:

Using elimination

7x+8y=-2

-20x-8y=-24

-13x=-26

x=2

7(2)+8y=-2

14+8y=-2

8y=-16

y=-2

(2,-2)
