X=1 any number is equal to 1
Answer:
Elimination isn't exactly the easiest for this situation. But since the equations are in the same form and not solved for the same variable, I would go with elimination. (If they were solved for the same variable, I would go with substitution.) It would require me to make a manipulation on both equations.
I would multiply first equation by 5 and second equation by -2. The reason I would do this is because the y's would have opposite coefficients and when you add opposites you get 0.
The new set of equations would look like this:
20x+10y=45
-14x-10y=2
But I will slope here since we aren't asked to solve it.
Some texts use the term linear combination instead of elimination. They are the same.
0.2 is the correct answer. All you have to do is divide 1 by 5 to get 0.2
Answer:
G=125 X + 
50
Step-by-step explanation:
Bob charges 125 pieces for each magical brooms . And 50 as one time charge .
We have to find the formula for the number of gold pieces G as a function of X.
Let X be the number of brooms he constructed
The charge for a broom stick is 125 . So the number of gold pieces he received when X brooms are constructed is 125 X
There will be 50 Gold pieces as one time charge
so the total number of gold pieces will be 125 X + 50
therefore G=125 X +50
