Question

X:(-5)=2целых 1/3. 15-x=-42​

Answer 1

х : (-5) = 2 целых 1/3                     15 - х = - 42

х : (-5) = 7/3                                    х = 15 - (-42)

х = 7/3 · (-5)                                    х = 15 + 42

х = - 35/3                                        х = 57

х = - 11 целых 2/3

Answer 2

I'm sorry, but the expression you provided seems to be incomplete or unclear. It appears to be a combination of equations and statements without proper context or formatting. Let's try to understand and solve each part separately:

1. X:(-5)=2целых 1/3: This expression is not standard mathematical notation, and "2целых 1/3" is not a familiar mathematical term. If you could provide more information or clarify the notation, I'd be happy to help you with this part.

2. 15-x=-42: To solve this equation for the variable x, we need to isolate x on one side of the equation. Here's how we do it:

Add x to both sides: 15 - x + x = -42 + x 15 = -42 + x

Next, isolate x by subtracting 15 from both sides: 15 - 15 = -42 - 15 + x 0 = -57 + x

Finally, to get the value of x, add 57 to both sides: 0 + 57 = -57 + x + 57 57 = x

So the value of x in the equation 15 - x = -42 is x = 57.

If you have any other questions or need further assistance, please provide more context or details, and I'll be glad to assist you.
