Question

Х+(х-6)=7-(111х+87)-х+7

Answer 1

x+x-6=7-111x-87-x+7

2x-6=7-111x-87-x+7

114x=7-87+7+6

114x=-67

x=-67^114

Answer 3

To solve the equation Х+(х-6)=7-(111х+87)-х+7, we can start by simplifying both sides of the equation.

Let's simplify the left side first: Х + (х - 6) can be rewritten as 2х - 6.

Next, let's simplify the right side: 7 - (111х + 87) - х + 7 First, distribute the negative sign to the terms inside the parentheses: 7 - 111х - 87 - х + 7 Combine like terms: -112х - 73

Now, our equation is simplified to: 2х - 6 = -112х - 73

To solve for х, we can start by isolating the variable on one side of the equation. Let's add 112х to both sides: 2х + 112х - 6 = -112х + 112х - 73 This simplifies to: 114х - 6 = -73

Next, let's isolate the constant term. We can do this by adding 6 to both sides: 114х - 6 + 6 = -73 + 6 This simplifies to: 114х = -67

Finally, we can solve for х by dividing both sides of the equation by 114: (114х)/114 = -67/114 This simplifies to: х = -67/114

Therefore, the solution to the equation Х+(х-6)=7-(111х+87)-х+7 is х = -67/114.
