Answer:
x=7
Step-by-step explanation:
Since this is a parallelogram, you can say that the 5x+3 will equal to 38 in this situation. 38-3 =35.
So the answer is 7

Let x be the number of animal shelters.
Then the amount donated to animal shelters= 8x.... a multiple of 8
Thus, we know that 80<86 [a multiple of 8]
Thus, the maximum animal shelter he donated=
The money he donated to the animal shelters= $80
Thus, money left after donation=86-80=$6

To find how many solution our system has, we are going to find the slope of each equation.
equation (1)
equation (2)
To find the slope, we are going to express both equations in the form:
where
is the slope
Notice that equation (1) is already in the form; from equation (1) we can infer that 
To express equation (2) in the form, we are going to add 
to both sides of the equation:
Now, we can infer that the slope of equation (2) is. Since both equations have the same slope, we are dealing with parallel lines; parallel lines don't intercept, so the system has no solutions.
We can conclude that the correct answer is the first choice: <span>no solutions</span>
