Question

28 : 2,8 + x - b - 10 + b =?

Answer 1

10 +Х -b +10 +b = X+20    )))))))))))))))))))

Answer 2

Let's simplify the expression step by step:

28 : 2,8 + x - b - 10 + b

First, let's divide 28 by 2.8:

28 ÷ 2.8 = 10

Now the expression becomes:

10 + x - b - 10 + b

The terms "-10" and "+10" cancel each other out:

10 - 10 = 0

So, the expression simplifies further:

0 + x - b + b

The terms "-b" and "+b" cancel each other out as well:

x + 0 = x

Finally, the expression simplifies to:

x

Therefore, the expression 28 : 2,8 + x - b - 10 + b simplifies to just "x."
