Chapter 2: Q. 7E (page 105)

Solve the equation. Check your solution.
$x - 2.2 = 3.2$

Short Answer

Expert verified

Solution of given equation is $x = 5.4$ .

Step by step solution

Step 1. Solve for value of x

$x - 2.2 = 3.2$

Adding $2.2$ on both sides, we get

$\begin{matrix} x - 2.2 + 2.2 = 3.2 + 2.2 \\ x = 3.2 + 2.2 \\ x = 5.4 \end{matrix}$

Step 2. Verification of our solution

For checking our answer, substitute $x = 5.4$ in given equation $x - 2.2 = 3.2$ .

On substituting, we get

$\begin{matrix} x - 2.2 = 3.2 \\ 5.4 - 2.2 = 3.2 \\ 3.2 = 3.2 \end{matrix}$

Step 3. Conclusion

Here, both sides of above expression are equal.

So, our answer is true.
