Answer:
a = 22.5
Explanation:
The initial expression is:
6(a - 5) = 105
So, first, we need to apply the distributive property on the left side of the equation:
6a - 6(5) = 105
6a - 30 = 105
Then, add 30 to both sides of the equation:
6a - 30 + 30 = 105 + 30
6a = 135
Finally, divide both sides by 6:
6a/6 = 135/6
a = 22.5
Therefore, the solution of the equation is a = 22.5
