Question

Thirteen less than twice a number is seventeen more than half the number. What is the number?​

Answer 1

Number is 4

Explanation:

Let the number be x

2x - 13 = x/2 + 17

2x - 13 = x + 34/2

2(2x - 13) = x + 34

4x - 26 = x + 34

4x - x = 34 - 26

3x = 12

x = 12/3

x = 4

Answer 2

20

Explanation:

2x-13 = x/2 +17

add -x/2

2x-x/2-13=x/2-x/2+17

2x-x/2 -13=17

add 13

2x-x/2 -13+13 =17+13

3x/2 = 30

multiply by 2

3x=2*30

divide by 3

x= 60/3

x=20
