Question

(a) Ali has t number of coins and Alisha has u number of coins. Three times the addition of double of Ali’s amount and 5 times of Alisha’s amount less 500

Answer 1

Ali has t number of coins and Alisha has u number of coins. Three times the addition of double of Ali’s amount and 5 times of Alisha’s amount less 500

From given we have,

The number of coins Ali has = t coins

The number of coins Alisha has = n coins

Three times the addition of double of Ali’s amount

2 × t + 2 × t + 2 × t

5 times of Alisha’s amount

5 × n

less 500

2 × t + 2 × t + 2 × t = 5 × n - 500

6 × t = 5 × n - 500

6t = 5n - 500

∴ 5n - 6t = 500
