Solve the following equation by the trial and error method.

a) [tex]3k + 14 = 4[/tex]


Sagot :

Certainly! Let's solve the equation [tex]\(3k + 14 = 4\)[/tex] step by step.

1. Understand the given equation:

We have:
[tex]\[ 3k + 14 = 4 \][/tex]

2. Isolate the variable term:

To isolate the term involving [tex]\(k\)[/tex], we'll first subtract 14 from both sides of the equation:
[tex]\[ 3k + 14 - 14 = 4 - 14 \][/tex]
This simplifies to:
[tex]\[ 3k = -10 \][/tex]

3. Solve for [tex]\(k\)[/tex]:

Now that we have [tex]\(3k = -10\)[/tex], we need to solve for [tex]\(k\)[/tex]. We do this by dividing both sides of the equation by 3:
[tex]\[ k = \frac{-10}{3} \][/tex]

4. Result:

Therefore, the solution for the equation [tex]\(3k + 14 = 4\)[/tex] is:
[tex]\[ k = -3.3333333333333335 \][/tex]

To summarize, we isolated the variable term by subtracting 14 from both sides and then solved for [tex]\(k\)[/tex] by dividing both sides by 3. The value of [tex]\(k\)[/tex] that satisfies the given equation is [tex]\(-3.3333333333333335\)[/tex].
