Question

Solve the equation. Check your solution.

$x+7=12$

Short answer

Solution of given equation is$x=5$.

Step-by-step solution

Step 1.  Solving for value of x

$x+7=12$

Subtracting $7$on both sides, we get

$\begin{array}{c}x+7-7=12-7\\ x=12-7\\ x=5\end{array}$

Step 2. Verification of our solution

For checking our answer, substitute $x=5$ in given equation $x+7=12$

On substituting, we get

$\begin{array}{c}x+7=12\\ 5+7=12\\ 12=12\end{array}$

Step 3. Description of step

Here, as both sides above expression are equal, our answer is true.
