Question

Solve by cross multiplication 2x-3y=6,x+y=1

Answer 1

Answer:

Step-by-step explanation:

Step 1: x=(6+3y)/2

Step 2: Replace x in equation 2 from above equation:

         (6+3y)/2+y=1

          6+3y+2y=2

           5y=2-6

          y=-4/5

Step 3: Find value of x from step 1 and 2 equation:

        x=(6+3*(-4/5))/2=9/5

Answer 2

Answer:

Step 1: x=(6+3y)/2

Step 2: Replace x in equation 2 from above equation:

        (6+3y)/2+y=1

         6+3y+2y=2

          5y=2-6

         y=-4/5

Step 3: Find value of x from step 1 and 2 equation:

       x=(6+3*(-4/5))/2=9/5
