Question

The equations 2x - 5y= -5 11x-5y = 15 9x+ 5y = 5 and 14x+ 5y = -5 are shown on the graph below.

Answer 1

Answer:

the right system is:

2x - 5y= -5

14x+ 5y = -5

Explanation:

2x - 5y= -5 (1)

14x+ 5y = -5 (2)

(1)+(2)→ 16x=-10 then x= -10/16 = -0.625 ≈ -0.6

Now ,Using equation (1) x = -0.625 then y = 0.75 ≈ 0.8
