Also, please include an explanation, I will give brainliest to you if you include an explanation and at least two problems. Thanks!!! ☺️ ☺️ ☺️ ☺️

Answer 1

Answer:

19. x = 5

This is because Elise need $20, so we are going to figure out x

First, subtract 10 by both sides

2x = 10

Then, divide both sides by two to isolate the variable

x = 5

5 cars is the minimum

================================================================

20. He can stay for 11 nights.

First we subtract 80 by both sides

20x = 220

Then we isolate the variable by dividing both sides by 20

x = 11

Answer 2

Answer:

Answer 19:- x = 5

Answer 20:- x = 11

Step-by-step explanation:

Answer 19:-

2x + 10 = 20

2x = 10

x = 5

Answer 20:-

80 + 20x = 300

20x = 220

x = 11
