Solve equation: <br> 8n-7=-12+3n
lutik1710 [3]

To solve this problem, the first thing we have to do is regroup the terms so that we can then subtract, simplify, subtract, and finally simplify again.

But first we must know.

<h3>¿What are the equations?</h3>

Equations are those mathematical equalities divided between two expressions which are called members and separated by their equal sign, in which known elements and unknown or unknown data appear, related by mathematical operations.

<h3>We solve the problem:</h3>
  • 8n - 7 = -12 + 3n
  • 8n - 7 = 3n - 12
  • 8n - 7 - 3n = -12
  • 5n - 7 = -12
  • 5n = -12 + 7
  • 5n = -5
  • N = -1

Now we must check our results.

8n -7 = -12 + 3n

8 × - 1 - 7 = -12 + 3 × - 1

- 8 - 7 = - 12 - 3

- 15 = - 12 - 3

- 15 = - 15

So, our results are correct, the answer is n = - 1

¡Hope this helped!

The sum of the interior angles of a triangle is 180

if there are 3 sides then there are 3 angles

180/3=60 so each interior angle has a measure of 60

9213x5 is a multiple of 9 find the value of x​
Lina20 [59]

Answer:

\boxed{\textsf{The value of x is \textbf{7}.}}

Step-by-step explanation:

Given that 9213x5 is a multiple of 9 and we need to find out the value of x .So the rule for divisibility for 9 is :-

<u>Test </u><u>for </u><u>Divisibility</u><u> </u><u>by </u><u>9</u><u> </u><u>:</u><u>-</u>

A number is divisible by 9 if the sum of the digits is divisible by 9 .

Here the sum of the digits is :-

\sf\implies Sum_{(digits)}= 9+2+1+3+x+5=\pink{20+x}

Now here to make 20 +x divisible by 9 is should be equal to 27 since 27 is the nearest smallest multiple of 9 .

\sf\implies 20 + x = 27 \\\\\sf\implies x = 27-20 \\\\\sf\implies\boxed{\pink{\sf x = 7 }}
