Answer:
-16.02
Step-by-step explanation:
I assume the "......" is a variable replacement. I will use x instead.
0.18 = x - - 18 + - 1.8
Negative + Negative = Positive
0.18 = x + 18 + - 1.8
Positive + Negative = Negative
0.18 = x + 18 - 1.8
Combine like terms
0.18 = x + 16.2
Subtract both sides by 16.2 to isolate the variable x
0.18 - 16.2 = x + 16.2 - 16.2
-16.02 = x + 0
-16.02 = x
Check your work:
Plug in -16.02 into the original equation
0.18 = -16.02 + 18 - 1.8
They should equal each other; let's check to make sure
0.18 = 1.98 - 1.8
0.18 = 0.18
They equal each other so our answer is correct
