Not sure what the question is.

9+2x=18

Subtract 9 from each side then ...

2x=9

x=4.5

Not sure if I answered correctly.

Anneliese · Answer 2

Since 9 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 9 from both sides.

2x=-9+18

Add - 9 and 18 to get 9.

2x=9

Divide each term in the equation by 2.

x = 9/2

Exact Form:

9/2

Decimal Form:

4.5
