2x + 2y = -2<br> 3x -2y = 12

PIT_PIT [208]

Answer:

$2x + 2y = - 2 \\ 3x - 2y = 12 \\ now \: add \: both \: equations \\ 2x + 2y + (3x - 2y) = - 2 + 12 \\ 2x + 2y + 3x - 2y = 10 \\ 5x = 10 \\ \frac{5x}{5} = \frac{10}{5} \\ x = 2 \\ \\ 2x + 2y = - 2 \\ 2 \times 2 + 2y = - 2 \\ 4 + 2y = - 2 \\ 2y = - 2 - 4 \\ 2y = - 6 \\ \frac{2y}{2} = \frac{ - 6}{2} \\ y = - 3 \\ now \: lets \: check \: whether \: this \: equation \: correct \\ 3x - 2y = 12 \\ 3 \times 2 - 2 \times - 3 = 12 \\ 6 + 6 = 12 \\ 12 = 12 \\ yes \: its \: correct$

Oduvanchick [21]

Given :

A hostel of 500 boys has provisions for 4 days.

To Find :

If the provisions were continued for 20 days, how many students have gone out of the hostel.

Solution :

Let, number of students left after 20 days are x.

Now, provisions are given by :

$\text{Provisions = Number of students}\times \text{Number of days}$

Also, provisions remains same.

So, initial provision = final provision

$500\times 4 = x \times 20\\\\x=100$

Therefore, 100 students have gone out of the hostel.

Hence, this is the required solution.
