Question

Find x, if two equations are given as x+2y =19 and 2x+6y = 48​

Answer 1

Answer:

We can solve the value for x simultaneously.

let,

x+2y=19

x= 19-2y______(i)

and  2x+6y= 48 ______(ii)

Put the value of x in (ii)

2( 19-2y) + 6y = 48

38 -4y +6y = 48

2y = 10

y = 5

Put the value of y in (i)

x = 19-2y

x = 19-2(5)

x = 9
