How do you solve #2x+9y=17#, #x=7-4y#?
Isaiah Anthonyx= -5
y= 3
Generally, you can solve linear systems in different ways:
- Graphing
- Substitution
- Elimination.
In this case, since x is already isolated in the second equation, we would use substitution.
Then solve for x using either equation (I picked the second one)

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
