Answer:
- Solution of equation ( q ) = <u>1</u><u>6</u>
Step-by-step explanation:
In this question we have given an equation that is <u>3 </u><u>(</u><u> </u><u>q </u><u>-</u><u> </u><u>7</u><u> </u><u>)</u><u> </u><u>=</u><u> </u><u>2</u><u>7</u><u> </u>and we have asked to solve this equation that means to find the value of <u> </u><u>q</u><u> </u><u>.</u>
<u>Solution : -</u>
<u>Step </u><u>1</u><u> </u><u>:</u> Solving parenthesis :
<u>Step </u><u>2</u><u> </u><u>:</u> Adding 21 on both sides :
On further calculations we get :
<u>Step </u><u>3 </u><u>:</u> Dividing by 3 from both sides :
On further calculations we get :
- <u>Therefore</u><u>,</u><u> </u><u>solution</u><u> </u><u>of </u><u>equation</u><u> </u><u>(</u><u> </u><u>q </u><u>)</u><u> </u><u>is </u><u>1</u><u>6</u><u> </u><u>.</u>
<u>Verifying</u><u> </u><u>:</u><u> </u><u>-</u>
Now we are very our answer by substituting value of q in the given equation . So ,
- 3 ( q - 7 ) = 27
- 3 ( 16 - 7 ) = 27
- 3 ( 9 ) = 27
- 27 = 27
- L.H.S = R.H.S
- Hence, Verified.
<u>Therefore</u><u>,</u><u> </u><u>our </u><u>solution</u><u> </u><u>is </u><u>correct</u><u> </u><u>.</u>
