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

Hey there! I'm happy to help!

We have twice the number.

2n

We want the sum of that and 13. Sum means to add.

2n+13

And this is 75.

Equation: 2n+13=75

We subtract 13 from both sides.

2n=62

We divide both sides by 2.

n=31

Have a wonderful day! :D

Step-by-step explanation:

n       - given number

2n     - twice the number

2n + 13    - the sum of twice the number and 13

Equation:

2n + 13 = 75

      -13     -13

 2n  =  62

  ÷2       ÷2

  n = 31

32/80  

91/140

the last one 54 doesn't go into 45. 54/100 ?
