Solve each system of equations using the method of substitution ot the method of elimination.
Answer to Problem 17RE
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:
We can use the elimination method to find the solutions of the system of equations.
Multiply both sides of the equation
So as to make the coefficients of
Add the equations
So, we get an equation containing two variables
We need another equation containing the variables
Multiply both sides of the equation
negatives of one number.
Add the equations
Divide both sides of the equation
Since, we get the same equation in both cases, we cannot find the exact value of the variables
Substitute
Hence, the solution, in ordered triplet form, is
