Question

2x + 4y = 1
3x - 5y = 7
solve the simultaneous equations x

Answer 1

Answer:

(x,y)=(3/2, -1/2)

Step-by-step explanation:

2x+4y=1  /*3

3x-5y=7  /*(-2)

6x+12y=3

-6x+10y=-14

...........................

/      22y=-11

      y= -11/22

     y= -1/2

2x+4*(-1/2)=1

2x-2=1

+2     +2

2x=3

x=3/2

so the solutionis (x,y)=(3/2, -1/2)
