Answer:
The Cost of yellow shirts is $15 and the cost of purple shirt is $ 60
Step-by-step explanation:
Let cost of one yellow shirt be x
and the cost of one purple shirt be y
On Monday
5x + 7y = 165--------------------(1)
On Tuesday
4x + 11y = 213----------------------(2)
To solve (1) and (2)
multiplying eq(1) with 4
20x + 28y = 660--------------------(3)
multiplying eq(2) with 5
20x + 55y = 1056-------------------(4)
Subtracting (3) from (4)
20x + 55y = 1056
20x + 28y = 660
(-)
-----------------------------------
0x +27y = 405
-----------------------------------
![y = \frac{405}{27}](https://tex.z-dn.net/?f=y%20%3D%20%5Cfrac%7B405%7D%7B27%7D)
y = 15
Substituting y value in eq(1)
5x + 7(15) = 165
5x + 105 =405
5x =405 -105
5x =300
x = \frac{300}{5}
x =60

Where is the picture for the question?
Answer:
![x=5](https://tex.z-dn.net/?f=x%3D5)
Step-by-step explanation:
To determine for which value of x a pair of expressions will be equal, we will need to set them equal to each other and then solve for x.
![3x-4=2x+1](https://tex.z-dn.net/?f=3x-4%3D2x%2B1)
First, we can add 4 to each side
![3x=2x+5](https://tex.z-dn.net/?f=3x%3D2x%2B5)
Now we can subtract 2x from each side
![x=5](https://tex.z-dn.net/?f=x%3D5)
Now, just to check our answer, we can plug in our answer back into the original equation to see whether we get the same result for each side
![3(5)-4=2(5)+1\\\\15-4=10+1\\\\11=11](https://tex.z-dn.net/?f=3%285%29-4%3D2%285%29%2B1%5C%5C%5C%5C15-4%3D10%2B1%5C%5C%5C%5C11%3D11)
A) -11 degrees
B) 77 degrees colder
