Question

5u+6v=11uv and 10u+9v=21uv find the value of u and v
send picture of solution

Answer 1

Step-by-step explanation:

5u+6v=11uv-----1

10u+9v=21uv-----2

10×5u+6v=11uv

5×10u+9v=21uv

50u+60v=110uv

50u+45v=105uv

-. -. -

________________

0u+15v=5uv

v=5uv/15

v=1/3uv

sub v=1/3uv in equation 1

5u+6(1/3uv)=11uv

5u+3uv=11uv

5u=11uv-3uv

5u=8uv

u=8uv/5
