Question

2 X + Y is equal to 14 and X + Y is equal to 8​

Answer 1

Answer:

Step-by-step explanation:

Given :

2x +y = 14....(1)

x +y = 8...(2)

from equation 1

2x + y = 14

2x = 14 -y

x = 14 -y /2 ...(3)

putting value of equation 3  ,in equation 2

x + y = 8

14 - y /2 + y = 8

14 - y + 2y /2 = 8

14 + y = 16

y = 16 -14

y = 4 ....(4)

putting value of y in equation in equation 2

x + y = 8

x + 4 = 8

x = 4
