Step-by-step explanation:

-3

Step-by-step explanation:

Remove the opposites and calculate but sense two opposites add up to zero, remove them from the expression and calculate the sum or difference

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.
