How do you solve 3/4x+1/2y=10 and 3/2xy=4?

Multiply both Eqs by 4 to eliminate the fractions:
Eq1: 3x + 2y = 40.
Eq2: 6x  4y = 16.
m1 = A/B = 3 / 2.
m2 = 6 / 4 =  3/2.
The lines have equal slopes which means they are parallel. In order to have a solution, the lines must intersect; but parallel lines do not
intersect. Therefore, there are no solutions.
