Question

If x = a, y = b is the solution of the equations x + y = 5 and 2x – 3y = 4, then the values of

a and b are respectively

(a) 6, -1

(b) 2, 3

(c) 1, 4

(d) 19/5, 6/5If x = a, y = b is the solution of the equations x + y = 5 and 2x – 3y = 4, then the values of

a and b are respectively

(a) 6, -1

(b) 2, 3

(c) 1, 4

(d) 19/5, 6/5​

Answer 1

Answer:

d

Step-by-step explanation:

a+b=5 multiple by 2 2a+2b=10......(i)

2a-3b=4........(ii)

subtracting ii from I

5b=6

b=6/5

a+6/5=5

a=5-6/5

a=19/5
