# How many solutions does this system have #2x +8y= 16, -3x +6y =30#?

See a solution process below:

Substituting gives:

Even though the second equation is also not in pure standard form we can write it as one.

The slope for this equation is then:

Because both slopes are different there is one solution to this system of equations.
