How to solve this?
x + 10y + z = 52
5x + y + 4z = 15
x + 2y - 3z = 12
31x + 12 - 24z = 117
18x + 24y + z = 151
12x - 6y + 4z = 116

Try reviewing your class notes and looking through your text book. Im sure that the answer you need is there. It might take a bit of thought to figure out how to do these problems! Take the time to figure it out, it will be worth it in the long run!

couple ways to do this:
Easiest way depending on what math course your in:
Set up a matrix .. the coefficients are the numbers you enter into the matrix. Before you enter those numbers into the matrix you must simplify all the equations and set them equal to zero.
You can use a graphing calculator to solve matricis.
Also you can solve for one variable and substitute it in :
x= 52-10y-z .. for all values of x you substitute 52-10y-z
then you do so for another variable. this is gonna get super long and is gonna take forever to solve. I'm guessing your in a linear algebra class or somthing like that so just use a matrix.

guess and check numbers for the variables
(ex: 2+X=3 ; 2+1=3 ; x=1)
