a system of equations is shown below: y=3x-7 and y=2x+7. what is the solution to the system of equations?

castortr0y [4]

A system of equations means that both equations need to be true in the same time.
Since y is equal with 3x-7 and 2x+7 then those must be equal with eachother.
3x-7=2x+7
3x-2x=7+7
X=14
Now that we know x use any given equation of y and substitute x with 14
Y=3•14-7=35
Solution: x=14, y=35

Athena bought x boxes of cookies to bring to a party. Each box contains 10 cookies. She decides to keep two boxes for herself. S

mash [69]

Given parameters:

Number of boxes Athena bought for the party = x

Number of cookies per box = 10

Number of cookies she brought to the party = 70

Number removed = 2 boxes

Unknown:

Equation of the number of boxes = ?

Solution:

1 box of cookies contains 10 cookies

If Athena, removed 2 boxes, in those two boxes, we have 20 cookies

Total number of cookies = 70 + 20 = 90 cookies;

So;

x = $\frac{total number of cookies}{number of cookies per box}$

Therefore;

x = $\frac{90}{10}$ boxes
