What does x-4over5=6over7   what doesx=

Answers

x-(4)/(5)=(6)/(7)

Pass the (4)/(5) but change the signal

x=(6)/(7)+(4)/(5)

now we have to make the minimum common multiple of 7 and 5, this number will be 35 therefore

x=(6*5)/(35)+(4*7)/(35)

x=(30)/(35)+(28)/(35)

now we can add both

x=(30)/(35)+(28)/(35)

x=(30+28)/(35)

\boxed{\boxed{x=(58)/(35)}}
