How much is 3h - 5h? ===>  -2h

Subtract 11 from both sides

-2h + 11 - 11 = 18 - 11

-2h = 18-11 = 7

h = -7/2

Understood? :)

Ohh okay! So let me get this straight: If there are two numbers left that don't go into each other, for example: 2x=3, the answer would be 2 over 3?

akashdeepdeb · Answer

If 2x = 3

And we only want the value of x then divide both sides by 2
Leaving us 2x/2 which is x because that's what we want... D:

So if 2x = 3
x = 3/2

If say 2x = 3 - 4x

Add 4x to both sides to get rid of the RHS 4x

2x + 4x = 3 - 4x + 4x
6x = 3
x = 1/2
