Question

fin of the point of intersection of lines
, 4x+8y-1=0; 2x - y+1=0.​

Answer 1

Step-by-step explanation:

subtract equation 1 from 2 with multiplication of 2 in equation 2....

(4x+8y-1)-2*(2x-y+1)=0-2*0

4x+8y-1-4x+2y-1=0

10y=2

y=1/5

putting the value of y in equation 2

2x-(1/5)+1=0

2x=(1/5)-1

2x=-4/5

x= -2/5 so the point of intersection is ( -2/5, 1/5)
