What is the difference between an expression and an equation?

• An expression has an equal sign, an equation does not

• An equation has an equal sign, an expression does not

• Equations are more difficult to solve

• Nothing, they are the same thing.

 $\left|v\ +\ 2\ \right|\ =\ 7$  

• No Solution

• v = 5

• v = -5, 5

• v = -9, 5

Solve for y:

5x + y = 7

• y = 5x + 7

• y = - 7 + 5x

• y = 7 - 5x

• y = -7 - 5x

Solve for h:

ah + 2h = p

• h = p - 2h

• $h\ =\ \frac{p}{a+2}$

• $h\ =\ \frac{a+2}{p}$

• h = a-2p
