What’s New Previously, you have just leamed about translating mathematical statement into algebraic expressions. This time, let us answer the activity below which will help us solve problems involving algebraic expressions. Activity 21 Find my message. Direction: Match each equation with the problem it represents. Write the equation and corresponding letter. Then write the letter of the equation in the table that has the problem number. Discover the message form by the letters. M 블 = 150 T X+8= 21 S a-12=25 D m-13=41 ol H c+10=35 4t=360 = 55 P A 28-18 1. Jeny has 8 more pens than Pete does. If Jeny has 21 pens, how many does Pete has? 2. Eliza is 12 years younger than Drexia. If Eliza is 25, how old is Drexia? 3. Jane has scored twice as many goals as Jacky has.

**Answer:**

1. x+8 = 21 – T

2. a-12 = 25 – S

3. 2s = 18 – A

4. m-13 = 41 – D

5. c/3 = 55 – U

6. p/2 = 150 – M

7. c+10 = 35 – H

8. 4t = 360 – P
