# How can I solve this? k/7+3-2k = 3-

Nov 29, 2017

$k = \frac{42}{13}$

#### Explanation:

$\frac{k}{7} + 3 - 2 k = - 3$

Multiply everything by 7 to eliminate the fraction:

$k + 21 - 14 k = - 21$

Isolate the variable:

$k - 14 k = - 21 - 21$

Simplify:

$- 13 k = - 42$

Divide both sides by -13:

$\therefore k = \frac{42}{13}$
