Question

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

Answer 1

`(2)/(3) + (3k)/(4) = (71)/(12)`

LCD ( 3 * 4 ) = 12

Multiply by LCD = 12


`(2)/(3) *12+ (3k)/(4) *12= (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= (63)/(9)`


`k=7`

hope this helps!
