Answer 1

$\huge{\boxed{\boxed{\underline{\rm{\purple{Answer}}}}}}$

Step-by-step explanation:

Let the 3 consecutive multiples of 7 be

• x, x + 7, x + 14

Given

x + x + 7 + x + 14 = 777

3x + 21 = 777

3x = 777 - 21

3x = 756

x = 756 / 3

x = 252

So the consecutive multiples are

x, x +7, x + 14

ie; 252, 252 +7, 252 + 14

252, 259,266 are the consecutive multiples.

Checking

x + x + 7 + x + 14 = 777

252 + 259 + 266 = 777

So, the answer is correct ✅

Answer 2

Answer:

The numbers are =258,259&260

Step-by-step explanation:

Let the three consecutive numbers are=x+1,x+2&x+3

x+1 + x+2 + x+3 =777

3x+6=777

3x=777-6

3x= 771

x=771÷3

x=257.

x+1=257+1=258

x+2=257+2=259

x+3=257+3=260

Verify=258+259+260=777.
