Question

What is the solution to the following equation? 3(X - 4)- 5 = X - 3 O A. X = 12 B. X = 8 O C. x=7 O D. *= 3

Answer 1

The initial equation is:

$3(x-4)-5=x-3$

Now we can distribute the 3 into the parenthesis so:

$3x-12-5=x-3$

Now we move all variable to the left of the equation and the constants to the right so:

$3x-x=-3+12+5$

Finally we simplify so:

$\begin{gathered} 2x=14 \\ x=\frac{14}{2} \\ x=7 \end{gathered}$

So the answer is C) x = 7
