Answer 2

`\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \bold{\left(2*\cfrac{x}{5}-9 + 9 \right) }\:\:\: \: \: \: \: \: \: \: \: \: \: \: \:`

`\: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: \bold{\cfrac{2x}{5}-9 + 9}`

For a problem like this, it is very easy, what should be done, you just have to put the 2 inside the fraction and since we see that there is less and more, you must proceed to the law of signs which is less and since 9 minus 9 is 0 0 is not taken into account, then the Result is as follows:

`\: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\: \: \: \: \: \: \: \: \:\bold{(2x)/(5)}`
