Answer 2

Answer:

x+4y=5 equation 1

Step-by-step explanation:

2x+6y=-10 equation 2

multiplying eq 1 with2 and eq 2 with 1 we get:

2x+8y=10 equation 3

2x+6y=-10 equation 4

by using elimination process we have

2x+8y=10

-2x-6y=10

solution

2y=20

y=10

putting value of y in equation 1 we have

x+4×10=5

40-5=-x

x=-35 ANSWER
