The equation to solve is:
[tex]X+7=-4[/tex]We need to solve for the variable X, which means to take X to one side and numbers to another.
In solving equations, remember this golden rule.
Side Change = Sign Change
Now, looking at the equation, we can keep X on the left hand side and take "+7" to the right hand side. So we are changing sides of "+7" so taking it to the right hand side, it becomes "-7", so:
[tex]\begin{gathered} X+7=-4 \\ X=-4-7 \end{gathered}[/tex]We know
-4 -7 = -11
Thus,
[tex]\begin{gathered} X=-4-7 \\ X=-11 \end{gathered}[/tex]The variable X is -11
