Question

Solve for k.

Answer 1

Hey there!

3/4k + 3/8k = 1/2

COMBINE the LIKE TERMS

(3/4K + 3/8k) = 9/8k

NEW EQUATION: 9/8k = 1/2

MULTIPLY 8/9 to BOTH SIDES

8/9 * 9/8k = 8/9 * 1/2

CANCEL out: 8/9 * 9/8 because it gives you 1

KEEP: 8/9 * 1/2 because it helps solve for your result (also known as giving you the result of the k-value)

NEW EQUATION: k = 8/9 * 1/2

SIMPLIFY IT AND YOU WILL HAVE YOUR RESULT

k = 4/9

Therefore, your answer is: k = 4/9

Good luck on your assignment and enjoy your day!
