I know its gotta be either 1 2 3 or 4.
Not sure what you mean by drag and drop but Im going to attempt this.
-3/5 = -12/20
1/5 = 4/20
That makes no sense. It should be -8/20 < 7/20?
Can you put the full problem or is that all the details provided?
The variable y is given.
now, substitute y in the second equation to get
-4x - (-4x-7) = 7
then we solve
first distribute
-4x+4x+7=7
combine like terms
0+7 = 7
7 = 7
because the answer is true, the solution to this system is “all real numbers”
