Answer:

The number is 7.

Step-by-step explanation:

Write out the equation.

2x+9=30-x

Move the variable, x, so both variables are on one side of the equation.

2x+9=30-x

+x +x

Subtract 9 on both sides to combine like terms.

3x+9=30

-9 -9

Divide by 3 on both sides to isolate the variable.

3x=21

3x/3=21/3

x=7
