Q1. - Algebra 2

Question

Write an equation whose solution is $-7$.

Step-by-Step Solution

Answer

The required answer is $7x=-14$.

Step 1- Determine the format of the equation

A variable with a coefficient 7 should be equal to double of 7 which is negative because the derived answer should be a negative number.

Step 2 – Form the equation

By using the obtained design of equation form the equation. 

$7x=-14$

Step 3- Make the conclusion

Divide by 7 on both sides of the equation to determine the solution of the equation.

 $\begin{array}{c}\frac{7x}{7}=-\frac{14}{7}\\ x=-7\end{array}$

As the solution of the formed equation is according to the   provided solution then the equation $7x=-14$ is the required equation.
