+247 well, we can replace k with x, so we get x-8/5=12. the formula is saying that if i take away 8/5 from a number and get twelve, what number did i start of with?. if you are taking away 8/5 from a number, it means that the number you are trying to work out is 8/5 bigger than the number you got. in other words, x-8/5=12 is the same as 12+8/5=x. you can even get rid of x to get 12+8/5. so, what is 12+8/5? I will leave that to you to figure it out.
