Answer 2

use the distributive property on each of the parenthesis.... so

16= 3x-3-x+7 ( you change the sign because you multiply by a negative )

combine like terms

16= 2x+4

Subtract 4 from each side

12=2x

Divide each die by 2

6=X

hope this helped :)

Answer 3

Distribute the 3 and the -1 on the right hand side to get

16 = 3x - x + 7 - 3

16 = 2x + 4

12 = 2x

6 = x
