Question

9+9x=10x+2 Solve for x

Answer 1

This problem is about linear equations.

To solve it, we need to find the value of x.

`9+9x=10x+2`

First, we need to organize the equation, all terms without variables at the right side, and all terms with variables at the left side

`9x-10x=2-9\text{ }\rightarrow-x=-7`

Finally, we multiply the equation by -1 to get the proper answer

`x=7`

Therefore, the answer is 7.
