Solve:
 $3x+15=3\left(x+5\right)$  

• No Solution

• x = 15

• All Real Numbers/Infinite Solutions

• x = 0

Solve for x:

• x = yb - v
• x = by - v
• x = by + v

Solve the literal equation for the given variable.

• 2A/h
• 2/(h)
• 2Ah
• Ah/2

Solve for h
$V\ =\ lwh$

• $V\ -l-w\ =\ h$

• $V-lw\ =\ h$

• $\frac{V}{lw}=\ h$

• $V-\frac{l}{w}=h$

Solve for a.

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