What is x plus 3 equals 5?

Answer 1

8

Answer 2

2

x+3=5

x=5-3

x=2

Another way to look at it:

In any algebraic equation, you have to remember the golden rule, which is "what you do to one side, you must do to the other". And in order to determine what x is, you have to do the reverse operation to both sides:

x + 3 = 5

x - 3 = 5 - 3

x = 2

Answer 3

x + 5 = -3

minus the 5 from both sides

this gives you:

x = 2

there is your answer!

Answer 4

x = -2
