Question

Please solve this quick 8n+7=31

Answer 1

Hello there!

To find the value of n, work to isolate it from all other terms in the equation.

8n+7=31 - Start by subtracting 7 from both sides. 8n + 7 - 7 = 31 - 7

8n = 24 Next, divide both sides by 8 to finish isolating n. 8n÷8 = 24÷8

n = 3

This is your final answer.

I hope this was helpful and have a great rest of your day!

Answer 2

For this case we must solve the following equation of first degree:

$8n + 7 = 31$

We subtract "7" on both sides of the equation:

$8n + 7-7 = 31-7\\8n = 24$

We divide between "8" on both sides of the equation:

$\frac {8n} {8} = \frac {24} {8}\\n = 3$

Thus, the value of the variable n is 3.

Answer:

$n = 3$
