# How do you solve #1/2x+y=5# and #-x-2y=4# using matrices?

##### 1 Answer

#### Answer:

There are no solutions; the equations represent two parallel lines which do not intersect.

#### Explanation:

If you multiply the first equation by

I you try to handle this as a matrix problem:

**using Cramer's Rule** (determinants)

but division by

**using Gauss-Jorden Method**

both the

which is clearly impossible.
