x+y=8;2x-6y=2 simultaneous equation
Answers
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
