Question

if x+y = 8 and 4y -x =2 then find the value of y​

Answer 1

Answer:

YOUR ANSWER IS Y=2...

Step-by-step explanation:

x + y =8            {equation 1}

4y - x = 2

4y = 2 + x

∴x - 4y =  -2           {equation 2}

SUBTRACTING EQUATION {2} FROM EQUATION {1},

      x + y = 8

-      x - 4y = -2

      5y = 10    

  ∴  y= 10/5

    ∴  y = 2

HENCE VALUE OF Y IS 2.
