Answer:
x = -1
Step-by-step explanation:
Isolate the variable (x). Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS = Parenthesis, Exponents (& roots), Multiplication, Division, Addition, Subtraction.
First, subtract 5 from both sides
5x + 5 = 0
5x + 5 (-5) = 0 (-5)
5x = 0 - 5
5x = -5
Next, divide 5 from both sides
(5x)/5 = (-5)/5
x = -5/5
-1 is your answer for x.

Subtract 5 from each side
5x+5-5 = 0-5
Divide by 5 on each side
5x/5 = -5/5
$18.5685 or $18.56
The answer is $18.56 because 123.79 multiplied by 15% is $18.56
I'm not sure if I did this right.
