Hello
I believe there is an error in the question
we have two equations and need to find x and y
let s multiply by 8 so that we can get rid of the fractions
(1) becomes 2x+4y=5
(2) becomse 6x-4y=9
if we sum it gives
2x+4y+6x-4y=9+5
8x=14
x = 14/8 = 7/4
and then from the first equation
4y = 5 - 7/4
<=> 16y = 20-7 = 13
y = 13/16
the solutions is (7/4,13/16)
Solution:
The end points of line segment UV is U(0, 3) and V(–4, –5).
The line segment is Partitioned by a point in the ratio of 4:3.Let that point be (x,y).
Formula for internal division
A line segment having end points divided by a point (x,y) in the ratio of m:n.
