In all things of nature there is something of the marvelous.

2. Remember when solving an algebraic equation:
1) Perform distributive property.
2) Combine like terms on each side.
3) Get all of the variables on one side of the equation.
4) Undo addition and subtraction, then multiplication and division.

3. Ex3) The width of a rectangle is 2 cm less than the length of the rectangle. The perimeter of the rectangle is 76 cm. Find the dimensions of the rectangle.

4. Ex4) Solve for w. V = lwh Ex5) Solve for g. S = ½gt2
Solving when there are multiple variables: Use the same techniques. Your answer will probably be a variable expression instead of a number.
Ex4) Solve for w.
V = lwh
Ex5) Solve for g.
S = ½gt2
