Writing How can you use substitution method to solve a system of equations that does not have a variable with a coefficient of 1 or -1?
To explain:How can you use substitution method to solve a system of equations that does not have a variable with a coefficient of 1 or -1?
Explanation of Solution
Given information:
system of equations that does not have a variable with a coefficient of 1 or -1.
Calculation:
If for the given system of equation does not have a variable with coefficients of 1 or -1 then first we have to make coefficient 1 or -1 and then we can solve as usually with same method.
By dividing coefficient with whole equation, we can make the coefficient of variable as 1 or -1.
For example: The given equation is
Dividing above equation by 5 we get
