Answer:
x =
Step-by-step explanation:
Given
3(x - 6) = 6 + 7, that is
3(x - 6) = 13 ← distribute parenthesis on the left side by 3
3x - 18 = 13 ( add 18 to both sides )
3x = 31 ( divide both sides by 3 )
x =

Let x be the number in the problem. When it states that x is "no more than -10", it means than it is less than or equal to -10. So, we have
x≤-10
In order to cancel out the on the left and isolate x, we multiply both sides by 
(since 
·=1). Thus, we have
x≤-10·=-15
Therefore, x≤-15
In order to cancel out the
x≤-10·
Therefore, x≤-15
