Question

Solve the equation. Check your solution.

$y-7.8=22.3$

Short answer

Solution of given equation is$y=30.1$.

Step-by-step solution

Step 1.  Solve for value of y

$y-7.8=22.3$

Adding $7.8$on both sides, we get

$\begin{array}{c}y-7.8+7.8=22.3+7.8\\ y=22.3+7.8\\ y=30.1\end{array}$

Step 2. Verification of our solution

For checking our answer, substitute $y=30.1$ in given equation $y-7.8=22.3$.

On substituting, we get

$\begin{array}{c}y-7.8=22.3\\ 30.1-7.8=22.3\\ 22.3=22.3\end{array}$

Step 3.  Conclusion

Here, both sides of above expression are equal.

So, our answer is true.
