Question

2u +15v=17uv and 5(u+v)=36uv​

Answer 1

Answer:

v=1/7 and u= 5

Step-by-step explanation:

2u+15v=17uv

divide by uv on both sides

2/v +15/u=17

now,5u+5v=36uv

divide by uv on both sides

5/v+ 5/u=36

Now,let 1/v=x and 1/u=y

2x+15y=17

5x+5y=36

on solving these equation

x=7 and y=1/5

so, v=1/7 and u=5

Answer 2

Answer:

U=5 And V=1/7

Step-by-step explanation:

2u+15v=17uv-------(1)

5u+5v=36uv--------(2)

Multiple 1 equation by 5

10u+75v=85uv----(3)

Multiple 2 equation by 2

10u+10v=72uv------(4)

So, now it will subtract with equation 3 and 4

10u+75v-10u-10v=85uv-72uv

65v=13uv

U=65÷13

U=5

Then putting the value of V

2u+15v=17uv

2×5+15v=17×5×V

10+15v=85v

10=85v-15v

10=70v

V=10÷70

V=1/7
