Question

E is 5 more than d.
fis 7 less than d.
a) Write an expression for e in terms of d.

Answer 1

C

Explanation:

Answer 2

e = d + 5

Explanation:

e = d + 5

f = d - 7

Solve for e means write as e = ...d

and this is already there...

You can not write it more compact then this.

If you try, you will notice you finally end with the initial equation which you started with, or you endup with something which is obviously very true like

e = e or d = d.
