Rearranging Equations

Area Formulas

200

Make H the subject

A = 1/2 x B x H

H = 2A/B

300

Make L the subject

A = L²

L = Sqrt[A] 

400

Make b the subject

A = ((a + b) x h)/2

b = (2A/h) - a 

500

Make r the subject

A = pi x r²

r = Sqrt[A/pi]

Money Maths

100

Make P the subject

I = P x R x T

P = I/(R x T)

400

Make r the subject

N = ((100 - r)/100)  x O 

r = -((N/O)x100 - 100)

500

Make r the subject

A = P x (1 +  r/100)²

r = 100 x (Sqrt[A/P] - 1)

Linear Equations

300

Make X the subject

Y = (X - 8)/6

X = 6Y + 8

400

Make X the subject

Y = (4X + 5)/13

X = (13Y - 5)/4

Temperature

100

Make C the subject

K = C + 273.15

C = K - 273.15

300

Make C the subject

F = C x (9/5) + 32

C = (F - 32) x 5/9

400

Make F the subject

K = (F - 32) x 5/9 + 273.15

F = (K - 273.15) x 9/5 + 32

500

Make v the subject

P = (m x v²)/r

v = Sqrt[(P x r)/m]
