Varia on Both Sides

Study the Example showing how to solve a linear equation

with the variable on both sides. Then solve problems 1-4.

Example

The weight of Keiko's kitten is the weight of her puppy. If each animal

gains 3 pounds, the kitten will weigh; as much as the puppy. The

equation ļw +3 = }(w + 3) describes this situation, where w is the weight

-+

of the puppy now. How much does the puppy weigh now?

6 W + 3) = 6.

3

• }(w + 3)

6 W + 3

= 2(w + 3)

W + 18 = 2w +6

w-w+ 18 = 2w - W+6

18 = w+6

12 = w

The puppy weighs 12 pounds now.

in the Example, how much will the kitten weigh if it gains 3 pounds?

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
