Chapter 4: Q78. (page 174)

Solve the equation and check the answer
$\frac{u}{- 2} = - 14$

Short Answer

Expert verified

The solution is $u = 28$ .

Step by step solution

Step 1 . Apply the concept of linear equation

In this, simply use the concept of solving the linear equation by doing various mathematical operations like addition, subtraction, multiplication or division.

Step -2 – Find the solution for u.

Here, the equation is $\frac{u}{- 2} = - 14$ .

Simply multiply both side by -2

$\begin{array}{l} \frac{u}{- 2} = - 14 \\ \frac{u}{- 2} \times - 2 = - 14 \times - 2 \\ u = 28 \end{array}$

Step -3 – Check the solution

The equation is $\frac{u}{- 2} = - 14$ .

Put $u = 28$ by taking Left Hand Side,

$\begin{array}{l} L e f t H a n d S i d e : \\ = \frac{u}{- 2} \\ = \frac{28}{- 2} \\ = - 14 \\ = R i g h t H a n d S i d e \end{array}$

The solution is correct.
