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?
