Answer:
<em>2 solutions</em>
Step-by-step explanation:
Given the expression
2m/2m+3 - 2m/2m-3 = 1
Find the LCM of the expression at the left hand side:
2m(2m-3)-2m(2m+3)/(2m+3)(2m-3) = 1
open the bracket
4m²-6m-4m²-6m/(4m²-9) = 1
Cross multiply
4m²-6m-4m²-6m = 4m² - 9
-12m = 4m² - 9
4m² - 9+12m = 0
4m² +12m-9 = 0
<em>Since the resulting equation is a quadratic equation, it will have 2 solutions since the degree of the equation is 2</em>

now we know
y+3=0
x-2=0
therefor
y=-3
x=2

Answer: $16
Step-by-step explanation:
reduce by 20% means cutting from 100% and leftover with 80% of original
100%-20%=80%
original price: $20×100%=$20
after reduction: $20×(100%-20%)=$16
