This is solved by setting up two equations and then using one to answer the other.
The first step (use what is given to set up the two separate equations)
We are looking for two numbers, let us call them X and Y.
We are told that X + Y = 59
We are also told that (9 more than) 9+ (4times the smaller number) 4Y is the bigger number X
Then we combine that into 9+4Y=X
so we now have two separate equations and we can use one to solve the other. Everywhere we have X in the first equation, we will fill in with the second equation
(9+4Y) +Y = 59 [then combine like terms]
9+5Y=59 [subtract 9 from both sides]
5Y=50 [divide both sides by 5 to isolate the Y]
Y=10 [now plug this into either equation to solve for X]
9+4(10)=X
9+40=X
<u><em>49=X and 10=Y</em></u>
B is true because 0-(-x) = 0 + x = x
Okay, so with the link we can tell this:
flour and baking soda are equal ratios
salt is one half the ratio of flour/baking soda
A: correct
flour and baking soda as equal ratios
B: incorrect
salt is at an incorrect ratio to flour
C: correct
salt is at a correct ratio to baking soda
D: incorrect
salt is at an incorrect ratio to baking soda
E: correct
baking soda is at a correct ratio to salt
answers: A, C , E

hope this helps!!!!!!!!!!!!
Answer:
10 and 7 are the numbers
Step-by-step explanation:
Let the number be x and y, ATQ, x+y=17 and x-y=3, solving it we will get x=10 and y=7
