Answer 3

It looks like you have an equation that you'd like help solving. The equation you provided is:

21x + 7x = 22,7

I see a couple of issues with this equation. First, there is a comma (,) instead of a decimal point (.) in the number 22.7. Second, there's an extra "7" at the end of the equation. Let's correct these issues and solve the equation:

The corrected equation is:

21x + 7x = 22.7

Now, we can simplify it by combining like terms:

(21 + 7)*x = 22.7

28*x = 22.7

Now, to solve for x, divide both sides of the equation by 28:

x = 22.7 / 28

x ≈ 0.8107 (rounded to four decimal places)

So, the solution to the equation is approximately x ≈ 0.8107. If you have any more questions or need further assistance, feel free to ask!
