Answer: n = 31

Step-by-step explanation: Remember that the word <u>sum</u> mean addition.

So the sum of twice a number and 13 means 2n + 13 = 75.

So our equation is 2n + 13 = 75.

Now let's solve the equation.

Start by subtracting 13 from both sides to get 2n = 62.

Now, divide both sides by 2 and we have n = 31.

Answer:

The answer is n = <u>31</u>

Step-by-step explanation:

Equation:   <u>2n + 13</u> = 75

2n = 75 - 13

2n = 62

n = 62/2

n = 31

check:

2*31 + 13 = 75

62 + 13 = 75
