Question

X+ (-12) = 3Answer here

Answer 1

To solve this equation the first step is to reduce the parenthesis:

$\begin{gathered} x+(-12)=3 \\ x-12=3 \end{gathered}$

Now, solve the equation for x, this is, isolate x to one side of the sign:

$\begin{gathered} x=3+12 \\ x=15 \end{gathered}$

x has a value of 15.
