Alenkasestr [34]
Hello, 

We know that if we make the same operation on both sides, we don't affect the equation:

For example:  
2=2 \\ 2\bold{+2}=2\bold{+2} \\ 4=4

Do you see? we add 2 on both sides and we don't affect the equality

We can do the same with the multiplication, for example

4=4   (i'll multiply both sides by 1/2) 
4*\bold{ \frac{1}{2}}=4*\bold{ \frac{1}{2}} \\ 2=2

Now, we do exactly the same in your excercise:

P=2(L+W) \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,[multiply\,\,by\,\,1/2] \\ \\ P*\bold{ \frac{1}{2}}=2(L+W)*\bold{ \frac{1}{2}} \\  \\ \frac{P}{2}=L+W\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,[Subtract\,\,L]\\  \\ \frac{P}{2}-\bold{L}=L+W-\bold{L}\\  \\ \frac{P}{2}-\bold{L}=L-\bold{L}+W \\  \\ \frac{P}{2}-L=W\\ \\ \boxed{ W= \frac{P}{2}-L }

soldier1979 [14.2K]
X - the full cost

75\%x=45 \\&#10;\frac{75}{100}x=45 \\&#10;\frac{3}{4}x=45 \\&#10;x=45 \times \frac{4}{3} \\&#10;x=15 \times 4 \\&#10;x=60

The full cost is £60.
