Literal Equations

Solve for y:
5x - y = 16

• -y = 5x + 16
• y = 5x + 16
• x = 5y - 16
• y = 5x - 16

Solve for n:
2m - n = 8

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

Solve:
12x - 4y = 20  ,  for   y 

• y = 3x - 5
• y = -3x + 5
• y = -3x - 5
• y = 3x + 5

Solve the equation for w.  
^{x = w / a}

• w = a / x
• w = x / a
• w = ax
• x = wa

What should we do first to solve for x?
y=mx+b

• Add
• Subtract
• Multiply
• Divide

a = b + c   , for  c

• c = a - b
• c = a + b
• c = ab
• c = a / b

Solve -2 = 4r + s for s.

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

Solve:
y = mx + b , for b

• y - mx = b
• y + mx = b
• y/mx = b
• y + mx = -b

Solve:
8x + 4y = 16    ,  for     y

• y = -2x + 4
• y = 2x - 4
• y = 2x + 4
• y = -2x - 4

5x - y = 16

• -y = 5x + 16
• y = 5x + 16
• x = 5y - 16
• y = 5x - 16
