Simplify the following inequality:

[tex]\[ 7(3e + 4) - (5e - 7) \leq 6 \][/tex]


Sagot :

Sure! Let's solve the inequality step by step:

Given inequality:
[tex]\[ 7(3e + 4) - (5e - 7) \leq 6 \][/tex]

Step 1: Distribute and simplify the expressions

First, distribute the 7 inside the parentheses:

[tex]\[ 7 \cdot 3e + 7 \cdot 4 = 21e + 28 \][/tex]

So now the inequality becomes:
[tex]\[ 21e + 28 - (5e - 7) \leq 6 \][/tex]

Next, distribute the negative sign:

[tex]\[ 21e + 28 - 5e + 7 \leq 6 \][/tex]

Combine like terms:

[tex]\[ (21e - 5e) + (28 + 7) \leq 6 \][/tex]
[tex]\[ 16e + 35 \leq 6 \][/tex]

Step 2: Isolate the variable (e)

Subtract 35 from both sides of the inequality to isolate the term with the variable [tex]\(e\)[/tex]:

[tex]\[ 16e + 35 - 35 \leq 6 - 35 \][/tex]
[tex]\[ 16e \leq -29 \][/tex]

Step 3: Solve for [tex]\(e\)[/tex]

Divide both sides by 16 to solve for [tex]\(e\)[/tex]:

[tex]\[ e \leq \frac{-29}{16} \][/tex]

Thus, the solution to the inequality is:

[tex]\[ e \leq -\frac{29}{16} \][/tex]

Hence, the final answer is:

[tex]\[ (-\infty < e) \ \text{and} \ (e \leq -\frac{29}{16}) \][/tex]
