The number is 15.
Step-by-step explanation:
Three times a number decreased by 10 is 35.
[tex] \\ \tt{}3x - 10 = 35[/tex]
What is the number?
[tex] \\ \tt{}3x - 10 = 35[/tex]
[tex] \\ \tt{}3x = 35 + 10[/tex]
[tex] \\ \tt{}3x = 45[/tex]
[tex] \\ \tt{}x = \frac{45}{3} [/tex]
[tex] \\ \boxed{\huge \boxed{ \tt{}x = 15}} \\ \\ [/tex]
Check to verify:
[tex] \\ \tt{}3(15) - 10 = 35[/tex]
[tex] \\ \tt{}45 - 10 = 35[/tex]
[tex] \\ \tt{}35 = 35[/tex]
