X=-1 and y=3
To solve this, because y is equal to 2x+5, you can substitute 2x+5 into the bottom equation for y.
You now have 3x - (2x + 5) =-6
This can be solved like a normal equation. Multiply each term in the parenthesis by -1.
3x - 2x - 5 = -6
Subtract 2x from 3x
x - 5 = -6
Add 5 to both sides
x=-1
Now you can solve for y by plugging -1 in for x in either equation. Im going to use the top one.
y= 2(-1)+5
y= -2+5
y=3
You can check your answer by plugging in the values for x and y into both equations and making sure both sides equal each other.

Add the boxes with each number to get the answer
Answer:
16 boxes of candy
Step-by-step explanation:
since 12 inches fit in one foot, 3 inches are basically 3/12 or 1/4
the volume of the locker = width x depth x height. 2x2x5=20
20 divided by 1 1/4=20 divided by 5/4=20*4/5=80/5=16
the domain of a function is the domain of its inverse -- This is False.
