x+y=150 and x-y=50 is
O 150 and 100
O 150 and 50
700 and 50
O 50 and 50​

Answer 1

Answer:

None of the above because if you add both the equations you will get the value for x which is 100 and then you can find value of y by substituting the value of x in any of the equations.

x=100

y=50

Answer 2

Answer:

(150,0)

Step-by-step explanation:

first assume the value of the x

x=150-y

put it in the 2nd one

150-y=150

-y=0

put this value in 1st one

x+0=150

x=150
