Question 63
A pair of linear equations which has a unique solution x = 2
andy = -3 is
Answer:
O x + y = -1 and 2x – 3y = -5
2x + 5y = -11 and 4x + 10y = -22
2x - y= 1 and 3x + 2y = 0
x - 4y - 74 = 0 and 5x + y - 13 = 0​

Answer 1

Answer:

(b) 2x+5y=-11 and 4x+10y=-22

Step-by-step explanation:

4(2)+10(-3)=-22 and 2(2) +5(-3) =-11

8+(-30)=-22 4+(-15) =-11

-22=-22 -11=-11

Answer 2

Answer:

O×2+(-3)=-1 and 2×2-3×-3=-5
