Answer 2

Answer:

d. 3

Step-by-step explanation:

19a - 17b = 55

a = (55+17b)/19

Now putting value of a in eq. 2...

17a - 19b = 53

17 x[ (55+17b)/19 ] - 19b = 53

(935 + 289b)19 - 19b = 53

After solving the equation...

b = -1

Now we can find the value of a by putting value of b in eq. 1

19a - 17(-1) = 55

19a + 17 = 55

19a =55-17

19a = 38

a = 38/19

a = 2

Now.. a - b = 2-(-1)

a-b = 2+1

a-b = 3
