Question

solve the pair of linear equations using cross multiplication method: 5x-2y=14 and -2x+y=-5 . Also, verify the solution​

Answer 1

Answer:

(x,y)=(4,3)

Step-by-step explanation:

b c a b= -2 -14 5 -2

1 5 -2 1

x/-10+14=y/28-25=1/5-4

x/4=y/3=1

x=4,y=3

Verification,in equation 1

5x-2y=14

5×4-2×3=14

20-6=14

Hence verified.....
