Answer:
The solution to the system of equations is
Explanation:
Giving the system of equations:
To solve this, we need to first of all eliminate one variable from any two of the equations.
Subtracting (2) from twice of (1), we have:
Subtracting (3) from 3 times (1), we have
From (4) and (5), we can solve for y and z.
Subtract 5 times (5) from 3 times (4)
Using the value of z obtained in (5), we have
Using the values obtained for y and z in (1), we have
