Question

how to solve 4=12x+40

Answer 1

Minus 40 on both sides. IMO, You need to do revision before you do those exercises/assignments.

Answer 2

if you are looking for x, transfer 40 on the other side.
4-40=12x
-36=12x
now you can solve for the value of x.

Answer 3

@alely There's no such thing as transferring 40 to other side. Please get your facts right.

Answer 4

@LXelle sorry we have different teachers. but not sorry because i know its right :)

Answer 5

Yeah, many teachers taught their students that way, which is he shortcut but the right way is to minus 40 on both sides, and not transferring to the LHS and RHS. There's no such thing. In mathematical reasoning if you were to write transfer to the LHS or RHS, you will get it wrong.

Answer 6

You don't have to be sorry, I don't lose anything.
