I do not know Devian or Amber?
You all have the same internet address and have asked very similar questions.
We must be taking the same class but different levels. I do not know a Devian or Amber.
Yeah! Right!

To solve this problem using a system of equations, we need to assign variables to the unknown quantities.
Let's assume:
Let the cost of 1 xylobar be x dollars.
Let the cost of 1 yackity be y dollars.
We are given the following information:
Jeejuu paid $1.88 for 4 xylobars and 1 yackity, so we can create an equation:
4x + 1y = 1.88.
We are also given that:
Dado paid for 1 xylobar and 2 yackities, so the total cost can be expressed as:
1x + 2y = ?.
We need one more equation to solve for x and y. For that, we can use the information given about imak's purchase:
imak bought 3 xylobars and 5 yackities, so the total cost can be expressed as:
3x + 5y = ?.
Now, we have our system of equations:
4x + y = 1.88
1x + 2y = ?
3x + 5y = ?
We can solve this system of equations using the substitution or linear combination method. Let's use substitution:
Step 1: Solve the first equation for y:
y = 1.88 - 4x
Step 2: Substitute this value of y into the second equation:
1x + 2(1.88 - 4x) = ?
Simplifying this equation gives us:
1x + 3.76 - 8x = ?
Combining like terms, we have:
-7x + 3.76 = ?
Step 3: Solve for x:
-7x = ? - 3.76
x = (? - 3.76) / -7
Now, substitute the value of x back into the first equation to solve for y.
At this point, we need the missing information about the total cost in order to find the exact values of x and y.
