I'm sorry to hear your stuck! Let''s learn how to do this.

Simplify both sides of the equation!

−25(10−x)=5x+50

(−25)(10)+(−25)(−x)=5x+50 - Distribute

−250+25x=5x+50

25x−250=5x+50

Now subtract 5x to each side.

25x−250−5x=5x+50−5x

20x−250=50

Add 250 to both sides. (We need to get x by itself)

20x−250+250=50+250

20x=300

Divide both sides by 20!

You get x = 15.

I'd take notes and look through on how this problem was solved for future references.

Have a good one!

Stells [14]
<h3>Given:</h3>

The ratio of number of girls and boys in a class of 30 students is 7:8

<h3>To Find:</h3>

The ratio of number of girls and boys if 5 new boys admit in the class.

<h3>Assumption:</h3>

Let the number of students be x.

<h3>Solution:</h3>

According to the question,

7x + 8x = 30

or, 15x = 30

or, x = \large {\tt {\frac{30}{15}}}

or, x = 2

7x = 7(2) = 14

8x = 8(2) = 16

There were 14 boys and 16 girls in the school.

After admitting 5 new boys, we get

14 + 5 = <u>19</u>

The ratio of number of girls and boys now is 16:19.

<h2>Answer:</h2>

<u>1</u><u>6</u><u>:</u><u>1</u><u>9</u>
