Answer:
x = 14
Explanation:
Let's solve your equation step-by-step. 
6(x − 5) = 54 
Step 1: Simplify both sides of the equation. 
6(x − 5) = 54 
(6)(x) + (6)(−5) = 54(Distribute) 
6x + − 30 = 54 
6x − 30 = 54 
Step 2: Add 30 to both sides. 
6x − 30 + 30 = 54 + 30 
6x = 84 
Step 3: Divide both sides by 6.
6x/6 = 84/6
x = 14
