Solving for Variables in Formulas

w=g+7
solve for g

• g=w/7
• g=w+7
• g=7w
• g=w-7

y=x-9
solve for x

• x=9-y
• x=9y
• x=y+9
• x=9/y

M=T-R
solve for T

• T=M+R
• T=M-R
• T=-R-M
• T=RM

Solve for a.

• a = pw
• a = p/w
• a = w/p
• a = w + p

Solve the literal equation for the given variable.

• 2A/h
• 2/(h)
• 2Ah
• Ah/2

Solve for y:
8x + 4y= 16

• y = -8x + 16
• y = 2x -4
• y = -2x + 4
• y = -8x + 12

Rewrite this formula and solve for the variable r. C = 2πr

• r = 2π / C

• r = C - 2 - π

• r = C - 2π

• r = C / 2π

• h = 2A / b

• h = A - ½b

• h = 2A - b

• h = A / b

pV = nRT
solve for R

• R= pV/nT
• R= p/n + V/T
• R= pV - nT
• R= (pV-n)/T

• r=7-ax

• r=7+ax

• r=7ax
