Answer 1

okay lets go through this together. i need you to answer my questions.

L = a+b correct?

Answer 2

subtract a from both sides and tell me what you get.

Answer 3

ok

Answer 4

go on. write the expression you get when you subtract a from both sides

Answer 5

L-a=b

Answer 6

right
so L-a = b
in other words
L minus a equals b
in yet other words,
b equals L minus a.
therefore b = L-a

Answer 7

sorry im retarded in math

Answer 8

I'm actually correct

Answer 9

what is the next step

Answer 10

and voila! you have an expression for b in terms of L and a.
in other words, you have successfully managed to express b using only L and a.
so if you have an expression like
15b, you can simply write it as 15(L-a) because b = L-a.

Answer 11

that is all there is to it.

Answer 12

I see can you help me with the other questions

Answer 13

I like how you explain things

Answer 14

Make math much easier for me
