To solve the given system of linear equations.
Answer to Problem 64PPS
Explanation of Solution
Given information: We have given a system of linear equations
Calculation: Let us solve the given system using Elimination method.
According to elimination method we need to eliminate a variable by adding or subtracting given equations in the system.
We need to make the coefficient same of a variable in both equations
Let us try to eliminate variable v .
Coefficient of v in first and second equation are 4 and -7. Least common multiple of 4 and 7 is 28. So, let us make both coefficients as 28 with opposite signs.
Therefore, multiply equation
Now, adding above equations and simplify
Divide both sides by 54, we get
Plug
Subtract 25 on both sides
Divide by 2 on both sides
Therefore, the solutions of system is
