You have the following equation:
[tex]x+10=-12[/tex]in order to solve for x, add -10 both sides of the equation and simplify, as follow:
[tex]\begin{gathered} x+10-10=-12-10 \\ x=-22 \end{gathered}[/tex]Then, x = -22
When you verify the equation by using the previous value of x, you obtain:
[tex]\begin{gathered} -22+10=-12 \\ -12=-12 \end{gathered}[/tex]Hence, the equation is consistent
