Question

Solve.

2x + 6 = 5

Answer 1

Favorite Answer

2x=5-6

2x=-1

x=-1/2

Answer 2

It's simple really. The whole point of solving is to isolate x, so:

1) Subtract 6 from both sides.

2x+6=5

2x+6-6=5-6

2x=-1

2) Divide both sides by 2.

2x/2=-1/2

x=-1/2

Answer 3

First subtract 6 from both sides (2x + 6 - 6 = 5 - 6 [remember, you have to subtract 6 from both sides or you will be changing the equation.]).

Then, to isolate the x, divide both sides by 2 (for the same reason above... you must do the operation on both sides or else you are changing the equation):

(2x/2)=(-1)/(2).

Hope that helps.
