Question

Solve for the variable X: X+7=-4 someone pls help what even is this

Answer 1

The equation to solve is:

`X+7=-4`

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:

`\begin{gathered} X+7=-4 \\ X=-4-7 \end{gathered}`

We know

-4 -7 = -11

Thus,

`\begin{gathered} X=-4-7 \\ X=-11 \end{gathered}`

The variable X is -11
