Answer: All of them have different values of x.
Step-by-step explanation:
Solve each individually.
[tex]12x-40=20\\12x=20-40\\12x=-20\\x=-\frac{20}{12}\\ x=-\frac{5}{3}[/tex]
------------------------------------------
[tex]-3x+16=1\\-3x=1-16\\-3x=-15\\x=\frac{-15}{-3}\\ x=5[/tex]
------------------------------------------
[tex]2x+4=18\\2x=18-4\\2x=14\\x=\frac{14}{2}\\ x=7[/tex]
------------------------------------------
[tex]10x-15=35\\10x=35+15\\10x=45\\x=\frac{45}{10}\\ x=\frac{9}{2}[/tex]
