We can simplify the expression by distributing the 2 and combining like terms:
-3.75 + 2(-4x + 6.1) - 3.25x
= -3.75 - 8x + 12.2 - 3.25x (distributing the 2)
= -11.75 - 11.25x (combining like terms)
Therefore, any expression that simplifies to -11.75 - 11.25x is equivalent.
Possible equivalent expressions are:
-3(-3.92x + 3.917)
-11.75 - 11.25(x+1)
-11.75 - 9x - 2.25x
-1.5(-15 + 9x)
11.25x - (11.75 + 2(-3.75))
Note that there are many other possible expressions that are equivalent to -3.75+ 2(-4x +6.1) - 3.25x, but the key is that they all simplify to the same value of -11.75 - 11.25x.
