Question

if x=2y and x-2k=-18 and y+k=11 find x+y​

Answer 1

Answer:

↪Value of x = 20

↪value of y = 10.

Step-by-step explanation:

➡Given here

x = 2y

✏x-2y = 0....(1)

✏x-2k= 18......(2)

✏y+k= 11......(3)

by (3),

k= 11-y ....(5)

[ keep value of k in (2) ]

x -2(11-y)= 18

↪x +2y = 18+22

↪x +2y = 40.......(6)

[ equations (1) + (2) ]

2x = 40

↪ x = 40/2

↪x = 20

[ by (1) ] yrr

20 -2y = 0

↪ 2y = 20

↪y = 20/2

↪y = 10

➡Thus:-

↪Value of x = 20

↪Value of y = 10
