Solve for K:
(1/3)k+(1/4)k=1

(1/3)k + (1/4)k = 1

k = 12/7

Step-by-step explanation:

step 1: use the multiplication property of equality

ex: 1/3k + 1/4k = 1

step 2: combine like terms (1/3k + 1/4k)

ex: 7/12k = 1

step 3: multiply each side by 12

ex: 7/12 * 12 = 1 * 12   (7k = 12)

step 4: divide both sides by 7

ex: 7k/7 = 12/7   (k = 12/7)

step 5: input your answer into your original equation to check your answer (k = 12/7)

ex: (1/3)(12/7) + (1/4)(12/7) = 1

4/7 + 3/7 = 1

7/7 = 1

1 = 1 (if this happens where a number equals itself like 1 = 1 then your answer is always true)
