Answer:
8 tables
Step-by-step explanation:
since she makes on average $18 per table and wants to make $180 we can just multiply $18 by 10 tables however we have to take into account the $36 she makes per night. 36 is just 18 multiplied by 2 meaning we can subtract a total of 2 tables away from the total of 10 tables to get 8 tables

Combine like terms:
subtract x from both sides to get
2x+5=14
subtract 5
2x=9

x=9/2
that's your final answer. unless your teacher wants you to put it in decimal form in which all you do is divide 9÷2.
