Open-Ended If you do not have equal coefficients for both variables, can you still use the elimination method? Explain.
To explain if we do not have equal coefficients for both variable, can we still use the elimination method.
Answer to Problem 11P
Yes.
Explanation of Solution
Yes we may still use the elimination method.
When coefficients are different for both variables we can make them equal by multiplying the whole equation with a constant.
For example let’s take two equations,
First be
Second be
Now we shall multiply whole second equation with 2 we get,
Hence the coefficients are equal now and we can apply elimination method.
