Question

4 /x + 3y = 8, 6/ x – 4y = -5 solve for x and y

Answer 1

Answer:

X and y=2

Step-by-step explanation:

in this equation the solution will be very big if we use fraction

therefore to remove fraction ;

let 1/X=a

then

4/X=4a and 6/X=6a

then equation will be

4a +3y=8. and 6a-4y=-5

to

to make y equal we will multiply veq.1 by 4 and eq.2 by 3

so,

eq.1 is now ..16a+12y=32

eq.2 is now...18a-12y-15

on adding...

34a=17

a=1/2

putting vale of a in original equation

1/X=a

1/X=1/2

x=2

y=2 on solving....

hope it helps....
