No solution

#9x+8y=15#
#9x+8y=30#

The above two equations are in the form

#ax+by=c#
This is a linear equation. Its slope is #m=-(a)/b#

Apply this formula in the above two equations.

#m=-9/8#

This is the slope of the two lines. The two lines are parallel.
Hence, the system of equations have no solution.
