Answer 1

Answer:

x + 4y= -4 ; 3y - 5x = -1 is the correct pairof simultaneous equations

Answer 2

Answer:

2x-3y=2 ; x+2y=8

Step-by-step explanation:

given : x =4 and y=2

Now put x= 4and y=2 in eq 1

2x-3y=2

2×4 - 3×2 = 2

8 - 6 = 2

2=2

Now put in eq 2

x+2y= 8

4+ 2×2 =8

4+4 =8

8=8

so, correct answer is option c.
