This is simple question but I kept getting -13 when the asnwer should be -7. I can't figure out what I am doing wrong.
I probably did it wrong, please correct! thanks so much!
5 = 3-k/4+6
5 = 3-k/-2
-10 = 3-k
-13 = k?
hmmm
I'm trying to interpret the problem. I'm going to assume that it is $\displaystyle 5=\frac{3-k}{4}+6$
First, subtract 6 from both sides to get $\displaystyle -1=\frac{3-k}{4}$
Now multiply both sides by 4 to get $\displaystyle -4=3-k$.
Solving for $\displaystyle k$, we see that $\displaystyle -7=-k\implies k=7$.
If the answer really is $\displaystyle k=-7$, then I think the problem would have to be $\displaystyle 5=\frac{3+k}{4}+6$
Does this make sense? If you have further comments or questions, please post back!
