[tex]\[ 6(x-4) + 7 = -5 \][/tex]

A. [tex]\( x = 2 \)[/tex]
B. [tex]\( x = 5 \)[/tex]
C. [tex]\( x = 4 \)[/tex]
D. [tex]\( x = 3 \)[/tex]


Sagot :

Sure, let's solve the equation step-by-step to determine the value of [tex]\( x \)[/tex]:

The given equation is:
[tex]\[ 6(x-4)+7=-5 \][/tex]

Step 1: Distribute the 6:
[tex]\[ 6(x-4) = 6x - 24 \][/tex]

So, the equation becomes:
[tex]\[ 6x - 24 + 7 = -5 \][/tex]

Step 2: Combine the constants on the left-hand side:
[tex]\[ 6x - 24 + 7 = 6x - 17 \][/tex]

So, the updated equation is:
[tex]\[ 6x - 17 = -5 \][/tex]

Step 3: Isolate the term with [tex]\( x \)[/tex] by adding 17 to both sides:
[tex]\[ 6x - 17 + 17 = -5 + 17 \][/tex]
[tex]\[ 6x = 12 \][/tex]

Step 4: Solve for [tex]\( x \)[/tex] by dividing both sides by 6:
[tex]\[ x = \frac{12}{6} \][/tex]
[tex]\[ x = 2 \][/tex]

Therefore, the solution to the equation is:
[tex]\[ x = 2 \][/tex]

Now let's match this solution with the given choices:

A. [tex]\( x = 2 \)[/tex]

B. [tex]\( x = 5 \)[/tex]

C. [tex]\( x = 4 \)[/tex]

D. [tex]\( x = 3 \)[/tex]

The correct answer is [tex]\(\boxed{A}\)[/tex], which corresponds to [tex]\( x = 2 \)[/tex].
