Question 653310
See how 2.7 is being added to both sides?  This will make this equation false.  For example:
5x + 15 = 3x + 15
5x = 3x (subtracted 15 from both sides)
This is an impossible statement.  We can't multiply the same number (x) by 5 and by 3 and have the results be equal to each other.

So the answer to your equation -4.0x + 2.7 - 1.6x = -4.6x + 2.7 is NO SOLUTION.
