Have you heard of the substitution method?

4. anonymous

yes but i dont know how to do it

5. pooja195

Ok so it already tells you what e equals right? On both equations ? right?

6. anonymous

right

Once we know that we can pick whatever equation we want to sub in lets choose equation 1 into equation 2 So heres how it would look $$\huge\rm\color{red}{4f + 1}=3f + 5$$
