Question

2/3+3k/4=71/12 How Do I Solve This?

Answer 1

$\frac{2}{3} + \frac{3k}{4} = \frac{71}{12}$

LCD ( 3 * 4 ) = 12

Multiply by LCD = 12

$\frac{2}{3} *12+ \frac{3k}{4} *12= \frac{71}{12} *12$

Refine :

$9 k + 8 =7$

Subtract 8 from both sides:

$9k+8-8 = 71-8$

$9k = 63$

Divide both sides by 9

$k= \frac{63}{9}$

$k=7$

hope this helps!
