CCSS.HSA.REI.A.1

What is the difference between an equation and an expression?

• Expressions are a complete thought. Equations are not resolved.

• Expressions have inequality symbols

• Equations have an equal sign to solve for the variable, expressions can only be simplified and evaluated.

• Equations only have one solution.

What is the most efficient way to solve

 $\frac{3}{5}x\ +\ 4\ =\ 7$  

• Add 4 to both sides, then subtract 7 

• Multiply both sides by 5

• Multiply both sides by 3/5

• Subtract 4 from both sides
