Solve each system of equations using the method of substitution ot the method of elimination.
Answer to Problem 18RE
It is inconsistent.
Explanation of Solution
Given information:
Solve each system of equations using the method of substitution or the method of elimination. If the system has no solution, say that it is inconsistent.
Calculation:
The given system of equations in three variables is given by the expressions given below.
The given system consists of three variables from which one of the variables is required to be removed from the equations. This can be done by multiplying first equations by
We can now obtain two equations in
Second equation from the first equation and by subtracting third equation from the first equation.
The given system of equations can be solved by the method of elimination. The first equation can be multiplied by
The coefficient of
The equations can now be solved for y since the coefficient of x is same in both the equations.
The above obtained results say that
