Question

pls solve this problem......​

Answer 1

Answer:

Step-by-step explanation:

I think the question is incomplete as

5x-3y=-5

the final equation

Answer 2

Answer:

X = 10

Step-by-step explanation:

Expanding along first row, for determinant

1*(5x-3y)= |A| = -5

5x-3y = -5

3y = 5x+5 = 5(x+1)

y = 5(x+1)/3  ....................... (i)

Now, since x and y are given as integers,

for y to be an integer x+1 should be a multiple of 3

=> x+1 = 3k   ( k is any integer )

From (i):   y = 5(x+1)/3 = 5*3k/3 = 5k

means, x is a multiple of 5

so according to options, x=10

HOPE IT HELPS...!!    :)
