Answer to Problem 90SR
The solution is (6,4)
Explanation of Solution
Given Information:
System of linear equations :
Concept Used:
Elimination Method for solving the linear equation:
In this , we either add or subtract the linear equations to get the resulting equation in one variable by elimination the other variable.
When the coefficients are opposite in sign , you add the equations and when the coefficients of the equations are same in sign , you subtract the equations.
Calculation:
- Given
- Solving it :
Multiplying equation (2) by -4, the coefficients of the x-terms are additive inverses .
So, the solution is (6,4)
