Question

Solve the equation. Check your solution.

$7x-3x=24$

Short answer

Solution of given equation is $x=6$.

Step-by-step solution

Step-1- Solve the equation for x

$7x-3x=24$

On simplifying, we get

$4x=24$

Dividing with $4$on both sides, we get

$\begin{array}{c}\frac{4x}{4}=\frac{24}{4}\\ x=\frac{24}{4}\\ x=6\end{array}$

$x=6$

Step-2-Verification of our solution

For checking our answer, substitute $x=6$ in given equation $7x-3x=24$.

On substituting, we get

$\begin{array}{c}7x-3x=24\\ \left(7\times 6\right)-\left(3\times 6\right)=24\\ 42-18=24\\ 24=24\end{array}$

Step-3- Conclusion

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