Hello!
The answer is z = 16..
Solve it like this..
#1) Regroup terms
-3 = -7+z/4 ---> -3 = z/4 - 7
#2) Add 7 to both sides.
-3 = z/4 - 7 ---> -3 + 7 = z/4
#3) Do the addition.
-3 + 7 = z/4 ---> 4 = z/4
#4) Multiply both sides by 4.
4 = z/4 ---> 4 * 4 = z.
#5) Do the multiplication.
4 * 4 = z ---> 16 = z
Hope this helps! ☺♥
2y/5 is the same thing as 2/5 times y so
14=2/5(y) then you divide both sides by y and you get
14/y=2/5 then from there multiply both sides by 1/14 to get
y=0.03

Here is what'd you do:
Ignore the $78.80 at the moment and focus on the $6.60 an hour and she worked 8 hours.
So, basically you'd do 6.60 * 8 (or 660*8 if you aren't allowed a calculator)
For 660*8 you'd get:
5280. move the decimal over twice.
$52.80 , if you are allowed a calculator you would have just done 6.60 * 8
So now you know she got $52.80 just working hourly.
Subtract $78.80 from $52.80
