Question

Elimination method of 2x+y=35,3x+4y=65

Answer 1

Answer:

Step-by-step explanation:

Elimination method is the easiest method

2x+y=35---------------Let eq 1

3x+4y=65--------------Let eq 2

equation 1 multiply by 3

equation 2 multiply by 2

now,6x+3y=105

       6x+8y=130

Then,change sign

       -     -        -

        -5y=-25

         y=-25/-5

          y=5

now put the value of y in either equation 1 or 2

           I want to put the value of y in equation 1

            2x+y=35

            2x+5=35

            2x=35-5

            2x=30

            x=30/2

            x=15
