Question

x+y=8;2x-6y=2 simultaneous equation​

Answer 1

Answer:

x+y =8 -------------(1)

2x-6y=2 ----------(2)

now multiply 2 in equation (1), we get

2x+2y=16 ----------(3)

now subtract equations (3) by (2)

2x+2y-2x+6y= 16-2

8y= 14

y= 14/8

y= 1.75

and now put the value of y in equation (1)

x+1.75=8

x=8 - 1.75

x=6.25

x=6.25 , y = 1.75
