Answer:
Total no. of sweets = 96
Step-by-step explanation:
Frank = 4x
Mary = 5x
Seth = 7x
7x = 4x + 18
7x - 4x = 18
3x = 18
x = 18/3
x = 6
No. of sweets Frank had = 4 × 6 = 24
No. of sweets Mary had = 5 × 6 = 30
No. of sweets Seth had = 7 × 6 = 42
Total no. of sweets = 96
Check ⇒
42 = 24 + 18
42 = 42
