Answer:

[tex]18+2x=42[/tex], [tex]2+18x=42[/tex], [tex]42-2x=18[/tex], [tex]2(x+18)=42[/tex], [tex]x+42=18+4x[/tex]

Step-by-step explanation:

First question:

He starts with 18, gains 2 every week, and needs 42. This means the equation is [tex]18+2x=42[/tex].

Second question:

He starts with 2, gains 18 every week, and needs 42. This means the equation is [tex]2+18x=42[/tex].

Third question:

It starts with 42, loses 2 every day, and needs 18. This means the equation is [tex]42-2x=18[/tex].

Fourth question:

Each friend has a total bill of 18+x, there are 2 friends, and they need 42. This means the equation is [tex]2(x+18)=42[/tex].

The only answer left is [tex]x+42=18+4x[/tex], so that's the answer to the fifth problem.
