The answer is -8 I believe.
To put this into an equation, we get 7x-x=-48. This is equal to 6x=-48. When we divide we get -8.
The answer is C), 834, 834.19, 834.2, 834.29
I know this is late, but I hope it was helpful!
When y=2 and y=5
1. 2y-1 and (3y-5+y or 4y-5)
when y=2 ; 2(2)-1 = 3 and 4(2)-5=3
when y=5 ; 2(5)-1 = 9 and 4(5)-5=15
----nonequivalent-----
2.5y+4 and (7y+4-2y or 5y+4)
so you don't have to place any value in because 5y+4 and 7y+4-2y are equal,
whatever you place any value in, it will be all the same then
-----equivalent------
and no need to find more
The Answer would be -6(3x-5).
