4x - 9 = 2x
Solve for x.
4x = 2x + 9
2x = 9
x = 4.5
We can plug 4.5 into the original equation to verify if it's correct.
4x - 9 = 2x
4(4.5) - 9 = 2(4.5)
18 - 9 = 9
The equation is true, and so x = 4.5

Answer:
Rosselyn: 22
Jacqueline: 10
Susan: 25
Step-by-step explanation:
$57 total
Jacqueline has the least.
Susan has the most. (15 more)
Rosselyn is in the middle. (12 more)
Susan has 3 more than Rosselyn.
57 - 12 - 15 = 30
(3.6x - 1.9)4 = 28.4
3.6x - 1.9 = 7.1
3.6x = 7.1 + 1.9
3.6x = 9
x = 9 / 3.6
x = 2.5 (value of x)
3.6(2.5) - 1.9 = 7.1 (side length)
you want to multiply it by 4 because right now its only showing one side. perimeter is all 4 sides combined
