1 point
x = 6/5, y = 19/5
x = 19/5 , y = 6/5
x = 5/7, y =7/9
None of these​

Answer 1

Answer:

(i) x + y =5 and 2x –3y = 4. By elimination method. x + y =5 ... (i). 2x –3y ... y = 6/5. Putting the value in equation (i), we get. x = 5 - (6/5) = 19/5. Hence, x ... 4y = 4. y = 4/4 = 1. Hence, answer is x = 2, y = 1. By substitution method.

Answer 2

Answer:

(b) x = 19/5, y = 6/5

Step-by-step explanation:

→ x + y = 5

→ x = 5 - y ..........................(1)

Also,

→ 2x - 3y = 4

Substitute value of equation (1) in above equation

→ 2(5 - y) - 3y = 4 [ From above (1) ]

→ 10 - 2y - 3y = 4

→ 10 - 5y = 4

→ -5y = 4 - 10

→ -5y = -6

→ y = 6/5

Substitute value of y in equation (1)

→ x = 5 - 6/5

→ x = (25 - 6)/5

→ x = 19/5

On solving x + y = 5 and 2x - 3y = 4 we get, x = 19/5 and y = 6/5.
