 Question from sena, a student: 2x/3+3y/2=-1 4x-5y=22 simultaneous equation

Hi Sena,

I think the challenge here is the fractions in the first equation. The left side has two fractions with denominators 2 and 3. The least common denominator is 6 and it is tempting to express the left side with this common denominator. I would not! Instead I would multiply both sides of the first equation by 6. The resulting equation together with the second equation gives you a linear system that I think you can solve. Make sure you verify your answer.
