Problem Solving
Linear equations are often used to solve practical problems that have an unknown quantity. We use a suitable pronumeral to represent the unknown quantity, translate the information given in the problem into an equation, and then solve the equation using the skills acquired earlier in this chapter.
Example 11
If a number is increased by 8, the result is 25. Find the number.
Solution:
Let x be the number. Increasing x by 8 gives x + 8, which we are told is 25. Therefore, x + 8 = 25. Subtract 8 from both sides to find x = 17. So, the number is 17.

The longest angle in a triangle is opposite the longest side. Similarly, the shortest angle in a triangle is opposite the shortest side. Knowing that...
<ACB is opposite to AB
<ABC is opposite to AC
<BAC is opposite to CB
We know that...
m<ACB < m<ABC < m<BAC
answer: m<ACB < m<ABC < m<BAC
