You can put this solution on YOUR website!
Which of the ordered pairs:
(3, 1), (0, -4), (-4, 0), (-3, -7)
are solutions for the equation x - y = 4?
:
For (3,1)
(3)-(1)=4
3-1=4
2=4 NOT TRUE
(3,1) is NOT a solution
:
For (0,-4)
(0)-(-4)=4
4=4 true
(0,-4) is a soltuion.
:
For (-4,0)
(-4)-(0)=4
-4-0=4
-4=4 NOT true
(-4,0) is not a solution
:
For (-3,-7)
(-3)-(-7)=4
-3+7=4
4=4 true
(-3,-7) is a soltuion
Happy Calculating!!!
