Answer» Answer: 30v+44u=10 40v+55u=13 multiply first dan by 4 and se condividi dan by3 Then SUBTRACT second EQN from first you will get (4×44-3×55)U=1 Simplify, you will get u=1/11 put this VALUE of u in any of the above eqn you will get v=1/5

Answer:

30v+44u=10

40v+55u=13

multiply first dan by 4 and se condividi dan by3

Then SUBTRACT second EQN from first

you will get (4×44-3×55)U=1

Simplify, you will get u=1/11

put this VALUE of u in any of the above eqn you will get v=1/5
