Solve the inequality:

[tex]\[ -1 \ \textless \ \frac{x+5}{5} - 1 \ \textless \ 2 \][/tex]


Sagot :

Certainly! Let's solve the inequality [tex]\(-1 < \frac{x+5}{5} - 1 < 2\)[/tex] step by step.

1. Separate the Given Inequality into Two Inequalities:

The compound inequality can be broken down into two separate inequalities:

[tex]\[ -1 < \frac{x+5}{5} - 1 \][/tex]

and

[tex]\[ \frac{x+5}{5} - 1 < 2 \][/tex]

2. Solve the First Inequality: [tex]\(-1 < \frac{x+5}{5} - 1\)[/tex]

- First, isolate the term [tex]\(\frac{x+5}{5}\)[/tex] on the right-hand side by adding [tex]\(1\)[/tex] to both sides:

[tex]\[ -1 + 1 < \frac{x+5}{5} - 1 + 1 \][/tex]

[tex]\[ 0 < \frac{x+5}{5} \][/tex]

- Next, multiply both sides by [tex]\(5\)[/tex] to eliminate the denominator:

[tex]\[ 0 \times 5 < \frac{x+5}{5} \times 5 \][/tex]

[tex]\[ 0 < x + 5 \][/tex]

- Finally, subtract [tex]\(5\)[/tex] from both sides to solve for [tex]\(x\)[/tex]:

[tex]\[ 0 - 5 < x + 5 - 5 \][/tex]

[tex]\[ -5 < x \][/tex]

3. Solve the Second Inequality: [tex]\(\frac{x+5}{5} - 1 < 2\)[/tex]

- First, isolate the term [tex]\(\frac{x+5}{5}\)[/tex] on the left-hand side by adding [tex]\(1\)[/tex] to both sides:

[tex]\[ \frac{x+5}{5} - 1 + 1 < 2 + 1 \][/tex]

[tex]\[ \frac{x+5}{5} < 3 \][/tex]

- Next, multiply both sides by [tex]\(5\)[/tex] to eliminate the denominator:

[tex]\[ \frac{x+5}{5} \times 5 < 3 \times 5 \][/tex]

[tex]\[ x + 5 < 15 \][/tex]

- Finally, subtract [tex]\(5\)[/tex] from both sides to solve for [tex]\(x\)[/tex]:

[tex]\[ x + 5 - 5 < 15 - 5 \][/tex]

[tex]\[ x < 10 \][/tex]

4. Combine the Results:

The two inequalities are:

[tex]\[ -5 < x \quad \text{and} \quad x < 10 \][/tex]

Combining these, we have:

[tex]\[ -5 < x < 10 \][/tex]

Therefore, the solution to the inequality [tex]\(-1 < \frac{x+5}{5} - 1 < 2\)[/tex] is:

[tex]\[ \boxed{-5 < x < 10} \][/tex]
