First you distribute what’s outside the parentheses (the -4)
-4•4= -4y
-4•-2= 8
New equation: -4y+8=12
Now you solve like a normal equation
12-8 is 4
New equation: -4y=4
Now divide
Answer:-1
Try making a proportion 10,000/1 and then 1000/x and solve
No, she will still owe $9.30. $25.63 - $16.33= $9.30
This is a problem where you should make an equation.
Let's say x is the first week. It would mean
First Week : x
Second Week : x + 5
Third Week : 2(x+5)
You need to add these up to make your equation. Your equation will look something like this :
![x+x+5+2(x+5) = 431](https://tex.z-dn.net/?f=x%2Bx%2B5%2B2%28x%2B5%29%20%3D%20431)
Now you simplify.
![2x+5+2x+10 = 431](https://tex.z-dn.net/?f=2x%2B5%2B2x%2B10%20%3D%20431)
![4x+15 = 431](https://tex.z-dn.net/?f=4x%2B15%20%3D%20431)
![4x = 416](https://tex.z-dn.net/?f=4x%20%3D%20416)
That means they sold 104 Boxes in the First Week.
So they sold 109 Boxes the Second Week.
109 x 2 = 218
And they sold 218 Boxes the Third Week.

Answer:
x = 4.1
Step-by-step explanation:
6x-3 + 3x+6 + 5x = 60
14x + 3 = 60
14x = 60 - 3
14x = 57
x = 57/14
x = 4.1
