Answer 1

URGENT!!! Which ordered pairs in the form (x, y) are solutions to the equation

7x−5y=28 ?

Solution - -

Fill (-1,-7)

7x-5y=28

7(-1)-5(-7)=28

-7+35=28.

28=28

L.H.S=R.H.S

HENCE OPTION ONE (-1,-7) IS CORRECT

Answer 2

Good Morning!!!

X = -1 and y = -7

7 ( -1 ) - 5 ( -7 ) = 28

-7 + 35 = 28

28 = 28

Hence, options a is correct one among all the four options.

Have a nice day ahead.
