Answer:
[tex]\large \boxed{8}[/tex]
Step-by-step explanation:
Let x = your number
Then 6x = your number multiplied by 6
and 6x + 7 = 7 added to that number
[tex]\begin{array}{rcrl}6x + 7 & = & 55 & \\6x & = & 48 & \text{Subtracted 7 from each side}\\x & = & \mathbf{8} & \text{Divided each side by 6}\\\end{array}\\\text{Your number is $\large \boxed{\mathbf{8}}$}[/tex]
Check:
[tex]\begin{array}{rcl}6(8) + 7 & = & 55\\48 + 7 & = & 55\\55 & = & 55\\\end{array}[/tex]
OK.
