Percy solved the equation by expanding the expression on the left-hand side, and this is incorrect
<h3>How to determine the true solution?</h3>
The equation is given as:
x^2 + 7x + 12 = 12
The first step in solving the equation is to equate the equation to 0.
i.e.
x^2 + 7x + 12 - 12 = 0
This given
x^2 + 7x = 0
From the question, Percy solved the equation by expanding the expression on the left-hand side
Hence, Percy's solution is incorrect

Hi! The answer for the first one is 500
50 times 9=450
10% is 50
50 times 10= 500
The original price was 500.
The discount was $50
For the second one the answer is $10
The discount was $7
10-7=3
10% is 1 , 30% is 3 and 70% is 7
