Solve for Variable in Each Equation

Solve for x:

• x = yb - v

• x = by - v

• x = by + v

What is the first step (after setting up your workspace) in solving this equation:
5x + 7 = 12

• Divide by 5

• Subtract 5

• Multiply by 7

• Subtract 7

Solve:
y = mx + b , for b

• y - mx = b

• y + mx = b

• ^y/_mx = b

• y + mx = -b

Solve:
a - b - c = 9 , for a

• a = b + c + 9

• a = b - c + 9

• a = -b + c + 9

• a = -b - c + 9

Solve:
d = rt   , for t

• d/r = t

• r/d = t

• d + r = t

• d - r = t

pV = nRT
solve for R

• R= pV/nT

• R= p/n + V/T

• R= pV - nT

• R= (pV-n)/T
