Sagot :

To solve the equation [tex]\(6(x - 3) + 7 = -5\)[/tex], we can follow these detailed steps:

1. Expand the terms inside the parenthesis:
[tex]\[ 6(x - 3) + 7 = -5 \][/tex]
Distribute the [tex]\(6\)[/tex] to both [tex]\(x\)[/tex] and [tex]\(-3\)[/tex]:
[tex]\[ 6x - 18 + 7 = -5 \][/tex]

2. Combine like terms on the left side of the equation:
[tex]\[ 6x - 11 = -5 \][/tex]

3. Isolate the variable term:
Add 11 to both sides of the equation to get:
[tex]\[ 6x - 11 + 11 = -5 + 11 \][/tex]
Simplifying, we get:
[tex]\[ 6x = 6 \][/tex]

4. Solve for [tex]\(x\)[/tex]:
Divide both sides by 6:
[tex]\[ \frac{6x}{6} = \frac{6}{6} \][/tex]
Simplifying, we find:
[tex]\[ x = 1 \][/tex]

Thus, the solution to the equation [tex]\(6(x - 3) + 7 = -5\)[/tex] is [tex]\(x = 1\)[/tex].

The correct answer is:
D. [tex]\(x = 1\)[/tex]
