Answer:
Let x represent the smaller number and y represent the larger number
<u>For the first equation </u>
Four times a number added to 3 times a larger number is 31 is written as
4x + 3y = 31
Making y the subject we have
3y = - 4x + 31
Divide both sides by 3
That's
![y = - \frac{4}{3} x + \frac{31}{3}](https://tex.z-dn.net/?f=y%20%3D%20%20-%20%20%5Cfrac%7B4%7D%7B3%7D%20x%20%2B%20%20%5Cfrac%7B31%7D%7B3%7D%20)
<u>For the second equation</u>
Seven subtracted from the larger number is equal to twice the smaller number is written as
y - 7 = 2x
Making y the subject
We have
<h3>y = 2x + 7</h3>
Hope this helps you
B is in the correct order
