MathematicsIn 4 + x5 ≤ 8, value of x is?

In $\frac{4 + x}{5} \leq 8$ , value of $x$ is?

A
$x \leq 36$
B
$x \geq 36$
C
$x \leq - 36$
D
$x \leq 39$

Solution:

To first get rid of the fraction while keeping the equation balanced, multiply each side of the inequality by

5

.

5 \times \frac{4 + x}{5} \leq 5 \times 8

5 \times \frac{4 + x}{5} \leq 40

4 + x \leq 40

In order to find x while keeping the equation balanced, remove

4

from either side of the equation as follows.

4 - 4 + x \leq 40 - 4

0 + x \leq 36

x \leq 36
