Question

What's X in 2x+4=9+x


PLEASE EXPLAIN​

Answer 1

Answer:

The answer is x = 5

Step-by-step explanation:

So we have to equation 2x + 4 = 9 + x.

2x + 4 = 9 + x

Subtract x to both sides of the equation (to get rid of the +x on the right side of the equation)

2x + 4 - x = 9 + x -x

Simplify

x + 4 = 9

Subtract 4 from both sides of the equation (to get rid of the +4 on the left side of the equation)

x + 4 - 4 = 9 - 4

Simplify

x = 5

The answer is x = 5

Answer 2

Answer:

x=5, see explanation below:

Step-by-step explanation:

2x+4=9+x

   -4  -4             Substract 4 from both sides: 4-4=0 | 9+x-4=5

2x=9+x-4

-x      -x              Subtract x from both sides: x-x=0 | 2x-x=1x

1x=9-4                9-4=5

1x=5                  Divide both sides by 1: 1/1=1 (but it just becomes x) | 5/1=5

---  ---

1     1

x=5                     x equals 5

Check:

2x+4=9+x

Substitute 5 for x:

2(5)+4=9+(5)

10+4=9+5

14=14

Therefore x does in fact equal 5

I hope this helped you.
