A. [tex]x = \frac{30}{17}[/tex]

B. [tex]x = -6[/tex]

C. [tex]x = -\frac{30}{17}[/tex]

D. [tex]x = 6[/tex]


Sagot :

To solve the equation [tex]\(-11x - 30 + 6x = 0\)[/tex] for [tex]\(x\)[/tex], follow these steps:

1. Combine like terms:
[tex]\[ -11x + 6x - 30 = 0 \][/tex]
Combine the [tex]\(x\)[/tex] terms:
[tex]\[ -5x - 30 = 0 \][/tex]

2. Isolate the [tex]\(x\)[/tex] term:
To do this, first move the constant term (in this case, [tex]\(-30\)[/tex]) to the other side of the equation. You achieve this by adding 30 to both sides:
[tex]\[ -5x - 30 + 30 = 0 + 30 \][/tex]
Simplifies to:
[tex]\[ -5x = 30 \][/tex]

3. Solve for [tex]\(x\)[/tex]:
Divide both sides by [tex]\(-5\)[/tex]:
[tex]\[ x = \frac{30}{-5} \][/tex]
Simplifies to:
[tex]\[ x = -6 \][/tex]

Therefore, the solution to the equation [tex]\(-11x - 30 + 6x = 0\)[/tex] is [tex]\(x = -6\)[/tex].

So, the correct answer is:

B. [tex]\(x = -6\)[/tex]
