Answer:
x+x+6-7+x and 3-x+2x-4+2x
Step-by-step explanation:
if you simplify the equation, it will be 3x-1 because you add the like terms
(6-7)+(-x+2x+2x)= (-1)+(3x)
so now you look at the equations listed and see which is simplified to 3x-1
a. (x+x+x)+(6-7)= 3x+(-1)=3x-1
b. (2x+x)+2= 3x+2
c. (3-4)+(-x+2x+2x)=(-1)+(3x)=3x-1
d. x-1
e. x+1
There were only two that resulted in 3x-1
