I want the answer to this problem<br> 3(x+2)-x=38
maks197457 [2]

Answer:

x = 16

Step-by-step explanation:

3(x+2)-x=38

Distribute

3x+6 -x = 38

Combine like terms

2x+6 = 38

Subtract 6 from each side

2x+6-6 = 38-6

2x = 32

Divide each side by 2

2x/2 = 32/2

x = 16

Write 5/3 as a mixed number
Lostsunrise [7]
5 / 3 is improper fraction.
To change it into mixed fraction you have to divide 5 by 3.
i.e. 1 is the quotient, 3 is the divisor, 5 is the dividend, and 2 is the reminder.

To write it in the mixed fraction you will only need the quotient, remainder and divisor.
First you will write quotient in the middle then the remainder divided by divisor
i.e. 1  2/3  where 1 is quotient, 2 is remainder and 3 is divisor.
