Solve the equation means to find the value of the variable in the equation
9 + x = -2 is an equation, to solve it find the value of x
To find the value of x we must keep x on one side and the other terms on the other side
We need to move 9 from the left side to the right side, to do that
Subtract 9 from both sides
[tex]\begin{gathered} 9-9+x=-2-9 \\ x=-11 \end{gathered}[/tex]The value of x = -11
The solution of the equation is x = -11
