Answer:
The solution set is: x>36
Step-by-step explanation:
We are given that we have to subtract 3 times of some number 'x' from 18 such that the resulting equation is less than -90.
this means that : 18-3x<-90
on solving the inequality by adding 3x on both side and adding 90 on both side we get that
108<3x
now on dividing both side by 3 we get that
x>36
Hence our solution set is: x>36
Addition is commutative.
3 + 4 = 7. = 4 + 3
Division is not commutative.
3 / 4 is not = 4 / 3.
The answer is -3. it is the only way to make the 6 negative
