Algebra Question
I only started solving algebra around 2-3 weeks ago and I am (yet again) having trouble with solving some of it.
Whilst happily doing my homework, I stumbled upon a division problem that looked like this:
g/5+1=4
I got as far as this (showing my work)
Step 1
v/5+1=4
-1 -1
Step 2
v/5=3
I know the answer, but my teacher still needs to see the work. What do I do? (PS: This is specific to algebraic division problems)
Thanks!

Re: Algebra Question
I don't understand your question.
This is how I show my work. And the teacher is fine with it:
v/5+1=4
v/5=3
v=15

Re: Algebra Question
You subtracted 1 from either side, not you must multiply each side by 5.

Re: Algebra Question
The answer is 19, if you are solving the equation through the P.E.M.D.A.S method (parenthesis, exponents, multiply, divide, add, then subtract).
I'm graduating HS this April and going to college in the Fall.

Re: Algebra Question
Yea, to solve variables, you have to go backwards. So you must do the opposite sign (or whatever its called 
)

Re: Algebra Question
laugh at me, but this is how you do it.
I color-coded each step.

Not in this case. Look, 15/5+1=4.

Re: Algebra Question
Hey illusionist, shouldn't you have multiplied 5 on both sides at the same time? Idk that's how I do it.
