Understanding the Equation

The given equation is $\frac{x}{6} + 7 = -1$ . To determine whether a value of $x$ is a solution to this equation, we need to isolate the variable $x$ and find its value. The equation involves a fraction, so we will need to use algebraic manipulations to solve for $x$ .

Step 1: Subtract 7 from Both Sides

To isolate the fraction, we start by subtracting 7 from both sides of the equation:

\frac{x}{6} + 7 - 7 = -1 - 7

This simplifies to:

\frac{x}{6} = -8

Step 2: Multiply Both Sides by 6

To get rid of the fraction, we multiply both sides of the equation by 6:

6 \times \frac{x}{6} = -8 \times 6

This simplifies to:

x = -48

Is x a Solution to the Equation?

Now that we have found the value of $x$ , we can determine whether it is a solution to the original equation. We substitute $x = -48$ into the original equation:

\frac{-48}{6} + 7 = -1

Simplifying this expression, we get:

-8 + 7 = -1

Which is true, since $-1 = -1$ . Therefore, $x = -48$ is a solution to the equation.
