Answer:

The answer would be k=5/2

Explanation:

2.5 (4k+2)12k <- distribute the 2.5 into the parentheses

10k+5=12k <- take the parentheses out of the equation

10k-12k= -5 <- Move the like terms to one side and change the sign

-2k= -5 <- Collect the like terms & divide by -2 on both sides of the equation

k=5/2 <- Answer at the end
