Question

F x3 = (5-F) x7 where F is the force in Newtons.
Determine the value of F ?

Answer 1

3f=35-7f
10f=35
f=3.5

Answer 2

\[\large F\times 3=7(5-F)\]
Expand the RHS [Right Hand Side]
\[\large 3F=35-7F\]
\[\large 10F=35\]
\[\large F=\frac{7}{2}\]

Answer 3

thanks for the prompt reply. took me a little longer than you guys but i got 3.5 too .cheers
