MATHEMATICS E3 algebra

y = – 5 – x

y = x + 5

y = x – 5

– y = x – 5

w = f+7m

w = f - 7m

-w = f + 7m

w= -f + 7m

$x=\frac{p-r}{2}$

$x\ =\ \frac{p+r}{2}$

$2x\ =\ p-r$

$2x\ =\ p+r$

 $t=\frac{2v}{5}$  

t=2v

 $\frac{2d+3}{tx}$  

2d= tx +3

 $d=\frac{tx-3}{2}$  

-2d= tx +3

 $tr=\sqrt{A}$ 

 $r^2=\frac{A}{t}$  

 $\frac{A}{r^2t}$  

 $r=\sqrt{\frac{A}{t}}$  

$a=\frac{v-u}{t}\$

$a=\frac{v+u}{t}$

$at=v-u$

$at=\ v+u$

m=gh

m=gh-P

$m=\frac{P}{gh}$

t = a/3t

a/3g

 $t=\frac{a}{3g-t}$  

A= $td^2$  

A=  $\frac{td^2}{4}$  

 $\frac{4A}{td^2}$
