How do solve the following linear system?: # y=-6x-9 , -9x+5y=1 #?
You can try by taking the value for
rearrange and solve for
we use this value for
Given the following linear system, you may choose from either performing the substitution method or the elimination method. For this example I would show both and it would be up to you to choose which method you are more comfortable with. However note that using any of the two aforementioned method would produce the same result.
For this method, since the
Since we now have the value of
In the same way, when we use the Elimination Method, we would arrive at the same answer.
Multiplying the first equation by 5
Adding the two equations to eliminate
Hence the ordered pair/solution to this linear equation is:
