16 points! the equation 1.6x − 2.2 = 1.4x can be transformed to form which of the following expressions? select one: a. 3.0x = 2.2 b. 0.2x = −2.2 c. 3.0x = −2.2 d. 0.2x = 2.2

The answer is D, 0.2x = -2.2

You must simplify the equation using SADMEP, the reverse order of operations in which subtraction is the first step. Your goal is to isolate the variable.

First, subtract 1.6 from each side:

1.6x - 2.2 = 1.4x
-1.6x           -1.6x
           

This will get you to 0x - 2.2 = -0.2x, or -2.2 = -0.2x

This is equivalent to 2.2 = 0.2x

So, the equation can be simplified to 0.2x = 2.2

Hope this helps, let me know if you need anything else! :)
