Carefully follow the steps to find the solution to the three equation system.
a. Use equations 2 and 3 and eliminate the by multiplication and addition, creating a new equation with only two variables.
b. Use equations 1 and 2 and eliminate the by multiplication and addition, creating a second equation with only two variables.
c. Use the two new equations, and eliminate the -variable by multiplication and addition, finding the value for the -variable.
d. Substitute -value in the second new equation and find the -value.
e. Substitute the and values into original equation 2 to find the -value
