7x-2y=20

Answer 1

Step-by-step explanation:

hopes above attachment helps you

Answer 2

Step-by-step explanation:

11x +15y = -23 -------(1)

7x-2y = 20 ----------(2)

multiply the eq.1 with 2 and eq.2 with 15.

22x + 30y = -46

105x- 30 y = 300

adding both eq after multiplication :

22x+30y= -46

105x-30y=300

______________

127x = 254

x = 2

putting the value of x in eq 2

7 (2)-2y = 20

14 -2y = 20

-2y = 6

y = 6/-2

Y = -3

x=2

y = -3
