Literal Equations

Solve for y:

y + 2 = 3x

• y = 2x + 3

• y= 3x +2

• y= 3x -2

• y= 6x

Solve IR = V for R.

• R = IV

• R = ^I/_V

• R = ^V/_I

• R = V - I

Solve:
4x + 2y = 1      , for    y

• y = -2x + ½

• y = 2x - ½

• y = 2x + ¼

• y = -2x + ¼

Solve for y:
5x - y = 16

• -y = 5x + 16

• y = 5x + 16

• x = 5y - 16

• y = 5x - 16

Solve:
C = 2πr, for r

• C/(2π) = r

• C + 2π = r

• C - 2π = r

• 2πC = r

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

• a = b + c + 9

• a = b - c + 9

• a = -b + c + 9

• a = -b - c + 9

Solve for x:

• x = yb - v

• x = by - v

• x = by + v

Solve for n:
2m - n = 8

• n = 2m - 8

• n = -2m - 8

• n = 2m + 8

• n = -2m + 8
