# How do you solve #2x+9y=17#, #x=7-4y#?

x= -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.
