Question

Solve each equation. Check your solution.

$y+14=-7$

Step-by-Step Solution

Answer

The required answer is $-21$.

Step 1- Isolate the variable y

Perform subtraction of 14 from both the sides of the equation.

$\begin{array}{c}y+14-14=-7-14\\ y=-21\end{array}$

Step 2 – Check the obtained value

Substitute the obtained value of y into the original equation and perform simplification for checking.

$\begin{array}{l}-21+14\stackrel{?}{=}-7\\ -7=-7\end{array}$

Step 3- Make the conclusion

As the checking results in equal values on both the sides on substation of obtained value which means that obtained value is correct.
