Question

Solution of linear equations 2x-y=0,8x+y=25 is

Answer 1

Answer:

2x - y = 0 ... (1)

8x + y = 25 ... (2)

by adding (1) & ( 2) equations,

we will get

10x = 25

x = 25/10 = 2.5

by putting the value of x in 1st equation

2x - y= 0..(1)

2 * 2.5 = y

5 = y

so, x = 2.5 & y = 5...

hope this will help you !
