Literal Equations Practice (3-A)

Solve for x:

• x = y - vb
• x = by - v
• x = by + v

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

• Add b
• Subtract b
• Multiply m
• Divide m

Solve the formula for y.  What is the 1st step? 

• Subtract B from each side.  
• Divide each side by Ax. 
• Divide each side by B. 
• Subtract Ax from each side. 

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 r.

• A
• B
• C
• D

• y=4w-10
• y=-2w+10
• y=2w-10
• y=-4w + 10

• g=(2.5+h)f
• g=1
• g=f(5+h)/2
• g=(5f+h) / 2

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

Solve:
4(2x + y) = 16    ,  for     y

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

Solve for m:
6m-15=mk+n

• m=(n+15)/(6-k)
• m=(6-k)/(n+15)
• m=(n+15)/k
• m=(n+15)/6
