The correct answer to the question is: Y=7x+42
Answer: $44,385
Step-by-step explanation: First multiply $385 by 49 which equals $18,865, and then subtract $18,865 from $63,250 to get $44,385.

<h2>Explanation will help you to understand better.</h2>
Step-by-step explanation:
Lets take an example to get to the answer.
Suppose, at the lunch time you are going to eat a cake, which you want to share with your friend equally. So, you have divided it in 2 equal parts. At the mean time your friend got stuck in somewhere else, and so you finished the cake all alone.
As you finished the whole cake, it means you ate the two equal parts.
It means you ate 2/2 part of the cake that is the whole cake.
Now, if you had divided the cake in 6 equal parts, then it would have called like 6/6 part of the cake.
Hence, 1 = 2/2 = 6/6.
Transforming equation systems into matrix form is fairly simple:
each column represents a variable, and each line represents an equation.
So in the first column, the NUMBERS MULTIPLYING by the X variables are put, in the second one the ones multiplying by Y, etc. The constants go after the vertical line, the last column
so we have:
![\left \{ {{x+y=5} \atop {3x-y=-1}} =\{ {{1x+1y=5} \atop {3x+(-1)y=-1}}\right](https://tex.z-dn.net/?f=%20%5Cleft%20%5C%7B%20%7B%7Bx%2By%3D5%7D%20%5Catop%20%7B3x-y%3D-1%7D%7D%20%3D%5C%7B%20%7B%7B1x%2B1y%3D5%7D%20%5Catop%20%7B3x%2B%28-1%29y%3D-1%7D%7D%5Cright)
So in a matrix, it will be the one on the picture
Showing fractions with models is giving a visual and sometimes can be easier to process.They also can be in picture form or other.Ex. A piece of pizza cut into fourths.
Showing fractions on a number line is also giving a visual but still allows you to add and subtract using numbers if that makes sense.Ex.
