Answer:

the system has a unique solution

Step-by-step explanation:

Start with an equation of a line in standard form,

[tex] ax + by = c [/tex]

Solve it for y to put it into the slope-intercept form:

[tex] by = -ax + c [/tex]

[tex] y = -\dfrac{a}{b}x + \dfrac{c}{b} [/tex]

The slope is -a/b.

Now look at your system of equations. The slope of the first equation is -a/b = -2/3. The slope of the second equation is -a/b = -6/5.

You have a system of two linear equations with two lines with different slopes, so the lines must intersect at a single point.

Answer: the system has a unique solution
