Isolating a Variable

• s = -Dn + C
• s = Dn - C
• s = Dn/C

F = ma
Solve for m

• Fa

• F/a

• a/F

• Infinity

a=3p+1
solve for p

• p=3a+1

• p=(a+1)/3

• p=(a-1)/3

• p=a+3

Solve the formula for t.  What is the 1st step? 

• Multiply each side by t. 

• Subtract f from each side. 

• Divide each side by t. 

• Add s to each side. 

Solve for y in terms of x: 3x - 4y = 10

• y = -3x + 10

• y = 0.75x + 2.5

• y = -3/4x + 10

• y = 3/4x - 2.5

Solve for x:

• x = yb - v

• x = by - v

• x = by + v

a = b + c   , for  c

• c = a - b

• c = a + b

• c = ab

• c = a / b

ax + c = R
(solve for x) 

• ax = R + c

• ax = R - c

• x = a(R-c)

• x = (R-c) / a 

Solve for y:
5x - y = 16

• -y = 5x + 16

• y = 5x + 16

• x = 5y - 16

• y = 5x - 16

IR = V
(solve for R) 

• R = IV

• R = ^I/_V

• R = ^V/_I

• R = V - I
