    ok forget misspheonix1’s explonation that was useless (no offence) y is the econd equasion multiplyed by 3?

  2. MissPheonix1 says

    so that the (-3y) + (+y) get rid of each other after you multiply the second equation by 3. Remember, when you have different signes (- and +) you add them…..so -3y + (+3y) gives you 0. so you can work out the value of x 🙂
