18k+26-8k=86 <br><br> I’m confused

Oksanka [162]

Answer:

$\Huge \boxed{K=6}$

Step-by-step explanation:

To solve this problem, first you have to isolate it on one side of the equation.

First, group like terms.

$\displaystyle 18k-8k+26=86$

Add.

$\displaystyle 18k-8k=10k$

$\displaystyle 10k+26=86$

Next, subtract 26 from both sides.

$\displaystyle 10k+26-26=86-26$

Solve.

$\displaystyle 86-26=60$

$\displaystyle 10k=60$

Then, divide by 10 from both sides.

$\displaystyle \frac{10k}{10}=\frac{60}{10}$

Solve.

$\displaystyle 60\div10=6$

In conclusion, the correct answer is k=6.
