Answer:
x = -7
How to:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
5°x-(2°x-9)=0
Pull out like factors:
21 + 3x = 3 • (x + 7)
Equations which are never true: Solve 3 = 0
<em>Solving a Single Variable Equation:</em>
Solve : x+7 = 0
Subtract 7 from both sides of the equation : x = -7
None of the answers are correct. The correct answer would be x=(P-25)/2
Multiplying by 0.01 to convert cents into dollars, we get:
570
600×0.95 = 570
I did this because if they made a 5% profit them you substrate that from 100 and divide the original price from what you get.
