Answer :

To solve the inequality [tex]\(6x + 5 + 2(4x + 1) > 6x + 9\)[/tex], follow these steps:

1. Expand and Simplify the Left Side:
[tex]\[ 6x + 5 + 2(4x + 1) \][/tex]
First, distribute the 2 inside the parentheses:
[tex]\[ 2(4x + 1) = 8x + 2 \][/tex]
Now, substitute this back into the inequality:
[tex]\[ 6x + 5 + 8x + 2 > 6x + 9 \][/tex]

2. Combine Like Terms on the Left Side:
[tex]\[ 6x + 8x + 5 + 2 > 6x + 9 \][/tex]
Simplify:
[tex]\[ 14x + 7 > 6x + 9 \][/tex]

3. Isolate the variable [tex]\(x\)[/tex]:
First, subtract [tex]\(6x\)[/tex] from both sides to remove the [tex]\(x\)[/tex] term from the right side:
[tex]\[ 14x - 6x + 7 > 6x - 6x + 9 \][/tex]
Simplify:
[tex]\[ 8x + 7 > 9 \][/tex]

4. Subtract 7 from Both Sides:
[tex]\[ 8x + 7 - 7 > 9 - 7 \][/tex]
Simplify:
[tex]\[ 8x > 2 \][/tex]

5. Divide by 8:
[tex]\[ \frac{8x}{8} > \frac{2}{8} \][/tex]
Simplify:
[tex]\[ x > \frac{1}{4} \][/tex]

Thus, the solution to the inequality [tex]\(6x + 5 + 2(4x + 1) > 6x + 9\)[/tex] is:

[tex]\[ x > \frac{1}{4} \][/tex]

In interval notation, this solution can be expressed as:

[tex]\[ \left( \frac{1}{4}, \infty \right) \][/tex]
