Question

Solve the problems
51+v=67
Solve for letter.

Answer 1

The letter is called the "variable", you should learn that terminology.
To solve these problems you "isolate the variable".

In this case what you need to do is subtract 51 from both sides, then v will be by itself.

Why don't you try that and tell me what you get?

Answer 2

i did

Answer 3

Answer 4

16

Answer 5

Nice! good job :)

Answer 6

I want to see if we get the same answer.

Answer 7

in that case you should just post the solution along with the question, like

Solve the problems
51+v=67
"I got 16, is that right?"

that saves us tutors some explanation and makes it look less like we are just doing your homework for you, which some people try to do.
