Answer :
Let's simplify the expression step by step:
1. Start with the innermost expression:
[tex]\[
5(x + 3)
\][/tex]
Distribute the 5:
[tex]\[
5x + 15
\][/tex]
2. Substitute and simplify the next expression:
Substitute [tex]\(5x + 15\)[/tex] into the expression [tex]\(2[x + 5(x + 3)]\)[/tex]:
[tex]\[
2[x + (5x + 15)]
\][/tex]
Simplify inside the brackets first:
[tex]\[
2[x + 5x + 15] \rightarrow 2[6x + 15]
\][/tex]
Now distribute the 2:
[tex]\[
12x + 30
\][/tex]
3. Substitute into the outer expression:
Substitute [tex]\(12x + 30\)[/tex] into the expression [tex]\(3[x - 2[x + 5(x + 3)]]\)[/tex]:
[tex]\[
3[x - (12x + 30)]
\][/tex]
Simplify inside the brackets:
[tex]\[
3[x - 12x - 30] \rightarrow 3[-11x - 30]
\][/tex]
Now distribute the 3:
[tex]\[
-33x - 90
\][/tex]
4. Add the constant from the original expression:
Finally, add 8 to the expression:
[tex]\[
8 + (-33x - 90)
\][/tex]
Simplify:
[tex]\[
-33x - 90 + 8 \rightarrow -33x - 82
\][/tex]
The simplified expression is:
[tex]\[
-33x - 82
\][/tex]

Finally, add 8 to the expression:
[tex]\[
8 + (-33x - 90)
\][/tex]
Simplify:
[tex]\[
-33x - 90 + 8 \rightarrow -33x - 82
\][/tex]
The simplified expression is:
[tex]\[
-33x - 82
\][/tex]
