Solving Literal Equations

Solve for n:
2m - n = 8

• n = 2m - 8
• n = -2m - 8
• n = 2m + 8
• n = -2m + 8

Solve for m:
6 = -3k - m

• m = 3k + 6
• m = -3k + 6
• m = 3k - 6
• m = -3k - 6

Solve for n:
5y = 8n - 7

• n =  ⅞y + ⅝
• n = 5y + 7
• n = ⅝y + ⅞
• n = ⅝y - ⅞

Solve for p:
2m + 5p = -4

• p = -2m - 4
• p = - ⅘m - ⅖
• p = ⅖m - ⅘
• p = -⅖m - ⅘

Solve for y:
8x + 4y = 12

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

Solve for y:
3x + y = 12

• y = -3x +12
• x = y + 4
• x = y + 12
• y = 3x -12

Solve for s:
 -2 = 4r + s

• s = -2 + 4r
• s = 2 - 4r
• s = -2 - 4r
• s = 2 + 4r

Solve the literal equation for the given variable.

• 2A/h
• 2/(h)
• 2Ah
• Ah/2

Solve for a.

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

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
