1) Carefully follow the steps to find the solution to the three equation system.
1.)2x-4y+3z=-7
2.)x+2y+z=15
3.)-3x+y+z=2
a. Use equations 2 and 3 and eliminate the z by multiplication and addition, creating a new
equation with only z and y.
b. Use equations 1 and 3 and eliminate the z by multiplication and addition, creating a second
equation with only and y.
c. Use the two new equations, and eliminate the y-variable by multiplication and addition,
finding the value for the x-variable.
d. Substitute x-value in the first new equation and find the y-value.
e. Substitute the x- and y-values into original equation 2 to find the z-value.
