2x+5y=100----------(1)
2x-6y=200‐-------(2)

solv the equation ​


Sagot :

Answer:

Step-by-step explanation:

2x+5y=100----------(1)

2x-6y=200‐-------(2)

NOW , 2x+5y=100

            2X=100-5Y

             X = (100-5Y)/2

SUBSTITUTING VALUE OF X IN EQUATION 2

          2(100-5Y)/2 -6Y = 200

            100-5Y -6Y =200

                Y = -100/11

SIMILIARY , X = 1400/11
