Question

(u/a)+(v/d)=1, (u/d)+(v/a)=1. find u and v

Answer 1

can someone please explain how to do this?

Answer 2

u/a = 1/2
u/d = 1/2

v/a = 1/2
v/d = 1/2

Answer 3

set
a = 2
d = 2
v = 1
u = 1

Answer 4

1/2 + 1/2 = 1

Answer 5

or

0.5 + 0.5 = 1

Answer 6

(u/a)+(v/d)=1 (1)

(u/d)+(v/a)=1 (2)



sorry i was going to write a detailed solution, but i have to go soon and do not have time

rearrange equation (1) to find u in terms of a,d,v

substitute into equation (2) (where ever you see u, you put your expression you just got from (1) )

rearrange to find v

sub back into (1) to find u

Answer 7

nice @Australopithecus

Answer 8

Look at what is changing in the equation and what is staying the same :)

Answer 9

then apply logic

Answer 10

but yes you can apply system of equations
