Question

I NEED HELP ASAP!!!!! I HAVE NO CLUE HOW TO DO THIS!!!!!!

Answer 1

z = 7

Explanation:

Change the mixed numbers into improper fractions, that is

z -
`(13)/(3)` =
`(8)/(3)`

Multiply through by 3 to clear the fractions

3z - 13 = 8 ( add 13 to both sides )

3z = 21 ( divide both sides by 3 )

z = 7
