Simplify 5x-3-7 to -2x-3
-2x-3=15-x
Add 2x on both sides
−3=15−x+2x
Simplify 15-x+2x to 15+x
−3=15+x
Subtract 15 on both sides
-3-15=x
Simplify -3-15 to -18
-18=x
X=-18

Jillian worked her 40 regular hours last week, plus 2 overtime hours at a time-and-a-half rate. Her gross pay was $516. What was
Effectus [21]

Its hourly rate of Jillian is 12 hours.

Here we have to find the hourly rate.

Let h be the hourly rate. As it is given that overtime is a time and a half rate.

So the overtime hour is 1.5h.

The total amount Jillian get is $516.

So from this, we get an equation:

40h + 2(1.5h) = 516

40h + 3h = 516

43h = 516

h = 12

Therefore we get the hourly rate as 12.

To know more about the equation refer to the link given below:
