Accepted Solution

A:

For this case we must solve the following equation:[tex]3 (x-7) = 42[/tex]Applying distributive property to the terms within the parenthesis we have:[tex]3x-21 = 42[/tex]Adding 21 to both sides of the equation:[tex]3x = 42 + 21\\3x = 63[/tex]Dividing between 3 on both sides of the equation:[tex]x = \frac {63} {3}\\x = 21[/tex]Answer:[tex]x = 21[/tex]
