Sana po may sumagot nito need ko na po talaga

Sagot :

1. Total savings = Savings on Monday + Savings on Tuesday

= 2x + 3y + 6x – y

= 2x + 6x + 3y – y

= 8x + 2y

Answer: Total savings = 8x + 2y

2. 14a² + 2a + 16 – (5a² – 9a + 7)

= 14a² + 2a + 16 – 5a² + 9a – 7

= 9a² + 11a + 9

Answer: There are 9a² + 11a + 9 girls in the classroom.
