Answer:
x = - 10
Step-by-step explanation:
Express the fractions on the left side as a single fraction.
Multiply the numerator/denominator of the first fraction by (x - 2)
Multiply the numerator/denominator of the second fraction by (x + 1)
+
= 3
Distribute the numerators and simplify
= 3 ( cross- multiply )
3x² - 2x + 4 = 3(x+ 1)(x - 2) ← distribute
3x² - 2x + 4 = 3(x² - x - 2)
3x² - 2x + 4 = 3x² - 3x - 6 ( subtract 3x² - 3x from both sides )
x + 4 = - 6 ( subtract 4 from both sides )
x = - 10

Answer:
$65
Step-by-step explanation:
Maia gets 20% discount and saves $13, that means,
20% of ORIGINAL PRICE is $13, right? Yes!
So, we can setup an equation in x (let original price be x) and solve for the unknown.
<em>20% of what number (x) is 13?</em>
<em />
This is what we want. Now remember, 20% converted to decimal is:
20% = 20/100 = 0.20
Now translation the "word equation" above to algebraic equation is:
0.20 * x = 13
<u>Note:</u> "of" means "multiplication" and "is" means "equal to"
Now, let's solve for x (original price):
The original price is $65
