Question

solve the following simutaneouly equation graphically

by full metode please any one geneus here

2x + 3y = 12 ; x - y = 1

Answer 1

This is the answer
hope that helps you

Answer 2

it is given x-y=1 so,
x=1+y
let 2x+3y =12 be equation 1
now, put the value of x in equation 1
that is, 2*(1+y)+3y=12
          2+2y+3y=12
         2+5y=12
        5y=12-2
       5y=10
       y=10/5
      y=2
 now, put the value of x in equation 1
 that is 2x+3*2=12
            2x+6=12
            2x=12-6
            2x=6
             x=6/2
              x=3
           
       
          hope this helps you
