Answer:

Step-by-step explanation:

9x + 2y = 59 -> 9x = 59 - 2y -> x = (59-2y)/9

2x + 5y = 4 -> 2(59-2y)/9 + 5y = 4 -> (118 - 4y)/9 +5y = 4

118 - 4y + 45y = 4*9 -> 41y = -82 -> y = -2, thus x = 7

What numbers are divisble by 23 but are between 2 and 10?

zloy xaker [14]

That is impossible.

For a number to be divisible by 23, it has to be greater than 23.

A number cannot be greater than 23, if you have restricted it to be within the numbers 2 and 10.
