2/3x + 5/2y = 15...if u dont want to mess with fractions, multiply this by the common denominator of 6....giving us : 4x + 15y = 90

so now we have..

4x + 15y = 12....multiply by -1

4x + 15y = 90

----------------

-4x - 15y = -12.....result of multiplying by -1

4x + 15y = 90

-----------------add

0 = 78......incorrect......there is no solution for this system of equations because ur lines are parallel
