• x = 4
• x = -4
• x = 2
• x = -2

Solve the equation
4x - 5x + 9 =5x - 9

• x = -3
• x = 9

S = 3F - 24  Solve for F

• F = (S + 24)/3
• F = S/3 + 24
• F = 3S + 24
• F = 3(S + 24)

pV = nRT
solve for R

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

Solving the formula P = 2L + 2W for W is not equivalent to which equation?

• (P-2L)/2 = W
• (P/2) - (2L/2) = W
• (1/2)P - L = W
• P - (1/2)L = W

Solve for y:
2x + 2y = 6

• y = - x + 3
• y = x + 3
• y = 2x +6
• y = - 2x + 6
