Concept explainers
Todescribe: Is only addition or subtraction used in elimination method.
Answer to Problem 9SGR
No, in elimination method sometimes division is also used.
Explanation of Solution
Given information:
The elimination method of system of equations.
The steps of performing elimination method are:
Step 1: Write each given equation in standard form
Step 2:Equate coefficients of one variable equal by multiplying coefficients of variables in both equations. Let for variable “ x ”
But some time if expression for one variable is given the division is also applicable.
Let a given system of equations is
From equation (2)
Dividing equation (1) by equation (3)
Thus, y gets eliminated and an equation in single variable “ x ” is obtained that can be solved easily.
Conclusion:
In elimination not only addition and subtraction is but sometimes division is also used.
