Answer:

Explanation:

given data

saves= 10p coins and 20p coins

total = 17 pounds

to find out

how 10p coins does he have

solution

we consider here no of 20p coin = x

so equation will be here

3 × 10 x +20 x = 1700

30 x + 20 x = 1700

x = 34

so that

10p coins = 3 time × 34 = 102

20p coins = 34

so that 10p coins does he have 102
