Answer:
-63/2
Step-by-step explanation:
6( -5 1/4)
= 6(-21/4)
= -63/2
Answer: 
Step-by-step explanation:
To solve for y, we want to isolate y.
[multiply both sides by y]
[subtract both sides by 3y]
[factor out y]
[divide both sides by (w-3)]
Now, we know that .
Answer:
We do not have the equation for the part B, so we can not aswer it correctly.
But i will give a general answer.
We could have infinite answers always when we have more variables than linear independent equations:
This is, if we have one variable, x, we can have infinite solutions if we have no equations (or equations with no restrictions for our variable)
So if we have an equation like:
x*4 = √16*x
you can see that both sides of the equation are exactly the same, so this equation actually does not have any value, and x could take infinite different values and the equation will remain true.
If we have two variables, x and y, we will have infinite solutions if we have only one equation:
y = a*x + b
We have infinite pairs (x, y)
