Chapter 4.4, Problem 4AGP

To determine

To calculate:To solve the equation and check the solution

Answer to Problem 4AGP

Solution is $x=14$

Explanation of Solution

Given information:Equation is $7=\frac{x}{-2}$

Calculation:

Given equation is as follows:

  $7=\frac{x}{-2}$

On solving the equation,

  $\begin{array}{l}\frac{x}{-2}=7\\ x=7\left(-2\right)\\ x=14\end{array}$

Now, in order to check the solution, substitute $x=14$ in equation $7=\frac{x}{-2}$

Right hand side of equation is solved as follows:

  $\begin{array}{l}\Rightarrow \frac{-14}{-2}\\ \Rightarrow 7\end{array}$

Since, Left hand side of equation is equal to right hand side

Thus, $x=14$ is solution of equation $7=\frac{x}{-2}$

Conclusion:

Hence,solution is $x=14$
