Question

Solve for the unknown 8k-2k=42

Answer 1

ANSWER

k = 7

EXPLANATION

The unknown variable in this equation is k,

$8k-2k=42$

To find its value, first, we have to combine like terms. This means that on the left side of the equation, we have to combine the coefficients of k,

$\begin{gathered} (8-2)k=42 \\ \\ 6k=42 \end{gathered}$

And then, divide both sides by 6,

$\begin{gathered} \frac{6k}{6}=\frac{42}{6} \\ \\ k=7 \end{gathered}$

Hence, the value of k is 7.
