Question

Write and solve an equation to find the number n. The sum of twice a number and 13 is 75.

Answer 1

Answer:

31 is n

Step-by-step explanation:

75=13+2n

75-13=62

62=2n

62/2=31

31=n

Answer 2

Answer:

Let the required number be "n"

According to the above problem,

$2n + 13 = 75 \\ 2n = 75 - 13 \\ 2n = 62 \\ n = \frac{62}{2} \\ \boxed{n = 31 }$

Therefore,

• n = 31 is the right answer.
