Ten times a number x is one half the sum of the number and three. Which answer represents this situation

Answer 1

x=1/3

Explanation:

10x = x+3

9x=3

x=1/3

Answer 2

10x = 1/2(x+3)

x = 3/19

Explanation:

10x = 1/2(x+3)

multiply by 2

2 * 10x = 1/2 * 2 (x+3)

20x = x+3

subtract x from each side

19 x = 3

divide by 19

x = 3/19
