Step-by-step explanation:
let the 1st number be x
given,
2nd number = 10 less than 1st number = x - 10
3rd number = 2 times the 1st number = 2x
their sum = 74
a/q,
x + x - 10 + 2x = 74
after solving the equation,
→ x + x - 10 + 2x = 74
→ 4x - 10 = 74
→ 4x = 74 + 10 = 84
→ 4x = 84
→ x = 84/4 = 21
therefore,
1st number = x = 21
2nd number = 10 - x = 21 - 10 = 11
3rd number = 2x = 2 × 21 = 42
hope this answer helps you dear......take care and may u have a great day ahead!
