Question

Solve the simultaneous equation
1/v +1/u = 1/5
1/v - 1/u = 2/5

Answer 1

Step-by-step explanation:

1/v+1/u=1/5

let the value of both v and u be similar [x]

1/x+1/x=1/5

2x=1/5X2

x=2/5 ➗2

x=1/5

Solve the other one by yourself

use this method only

Answer 2

Adding both equations

1/v+1/u+1/v-1/u=1/5+2/5

2/v=3/5

v=10/3

Similarly subtracting equation 2 from equation 1

2/u=-1/5

u=-10
