Answer:
10 and 14
Step-by-step explanation:
Let the first number be x and the second number be y, then
x + 18 = 2y → (1)
y + 16 = 3x → (2)
Rearrange (1) expressing x in terms of y by subtracting 18 from both sides
x = 2y - 18 → (3)
Substitute x = 2y - 18 into (2)
y + 16 = 3(2y - 18) ← distribute
y + 16 = 6y - 54 ( subtract 6y from both sides )
- 5y + 16 = - 54 ( subtract 16 from both sides )
- 5y = - 70 ( divide both sides by - 5 )
y = 14
Substitute y = 14 into (3) for corresponding value of x
x = (2 × 14) - 18 = 28 - 18 = 10
The 2 numbers are 10 and 14
Meredinth takes 24 minutes to reach her friend house
<em><u>Solution:</u></em>
Given that, Meredith lives 24 blocks from her friends house
She travels one block every minute
<em><u>To find: time taken by Meredith to reach friend house</u></em>

Number of blocks between Meredith house and her friedn house = 24
She travels one block every minute
Thus she takes 1 minute for 1 block
One block = 1 minute
So, for 24 blocks, we have to multiply by 24
Thus Meredinth takes 24 minutes to reach her friend house
