Question

solve 2x+y=5 : 3x-y =5.

Answer 1

Answer:

x = 2, y = 1

Step-by-step explanation:

2x+y=5

x = 5-y/2

Then, 3x-y = 5

=> 3(5-y/2) - y = 5  (Putting the value of 'x')

=> 15-3y/2 - y = 5  (Opening the brackets)

=> 15-3y-2y/2 = 5  (Taking LCM as 2)

=> 15-5y/2 = 5

=> 15-5y = 5 × 2

=> -5y = 10-15

=> y = -5/-5

=> y = 1

=> 3x-y = 5

=> 3x - (1) = 5  (Putting the value to 'y')

=> 3x - 1 = 5

=> x = 5+1/3 = 6/3

=> x = 2
