Changing the subject of the formula

Make w the subject of the formula

y = 3w - a

• $w\ =\ 3\left(y-a\right)$

• $w\ =\ 3\left(y+a\right)$

• $w\ =\ \frac{y+a}{3}$

• $w\ =\ \frac{y-a}{3}$

Make w the subject of the formula
 $s\ =\ \frac{w}{a}$  

•  $w\ =\ sa$  

•  $w\ =\ \frac{a}{s}$  

•  $w\ =\ \frac{s}{a}$  

•  $w=a\ -\ s$  

Make u the subject of the formula

v = u + 10t

• $u\ =\ \frac{v-10}{t}$

• $u\ =\ \frac{v+10}{t}$

• $u\ =\ v\ +\ 10t$

• 
  

  $u\ =\ v\ -\ 10t$
  

Make t the subject of the formula

v = u + 10t

• $t\ =\ \frac{u-v}{10}$

• $t\ =\ \frac{v-u}{10}$

• $t\ =\ \frac{u-10}{v}$

• $t=\ \frac{v-10}{u}$

P = 6x + 2

Express x in terms of P

• $x\ =\ \frac{P-2}{6}$

• $x=\frac{P+2}{6}$

• $x\ =\ \frac{P+6}{2}$

• $x\ =\ \frac{\left(P-6\right)}{2}$

Make x the subject of the formula

5 + m = x + p

• $x=5+m+p$

• $x=5+mp$

• $x\ =\ 5\ +\ m\ -\ p$

• $x\ =\ \frac{5+m}{p}$

s = hm

Express m in terms of s and h

• $m=sh$

• $m=\frac{1}{hs}$

• $m=\frac{h}{s}$

• 
  

  $m\ =\ \frac{s}{h}$
  

Make g the subject of the formula
a =  $\sqrt{g}$  

•  $g=\sqrt{a}$  

•  $g=a_2$  

•  $g=a^2$  

•  $a=g^2$  

Make  $\pi$  the subject of the formula
C =  $\pi d$  

•  $\pi=\frac{C}{d}$  

•  $pi=\frac{C}{d}$  

•  $\pi=\frac{d}{C}$  

•  $\pi=Cd$  

Make radius the subject of this formula
A =  $\pi r^2$  

•  $r=\sqrt{\frac{\pi}{A}}$  

•  $r=\sqrt{\frac{A}{\pi}}$  

•  $r=A\pi^2$  

•  $r=\sqrt{A\pi}$
