Answer:
x = 21
Step-by-step explanation:
8 + 3x = 29 + 2x
8 + 3x - 2x = 29
8 + x = 29
x = 29 - 8 = 21
x = 21
Answer: 71 coins
Step-by-step explanation:
First and foremost, we should note that:
12 months = 1 year
2 years = 12 × 2 = 24 months
Since she has 25 coins in her first month and adds 2 coins to her monthly collections, this means that she has 23 more months. This can be expressed as:
= 25 + 2x
where, x = number of months
= 25 + 2(23)
= 25 + 46
= 71 coins
She will have 71 coins after 2 years.
