Answer 1

256+х=478-143

256+х=335

х=335-256

х=79

Answer 2

Решение:
478-(256+х)=143
478-256-х=143
-х=143-478+256
-х=-79
х=79
Ответ:х=79

Answer 3

To solve the equation, we need to find the value of the variable "x." Let's start by simplifying the left-hand side of the equation:

478 - (256 + x) = 143

First, perform the operation inside the parentheses:

478 - 256 - x = 143

Now, subtract 478 and 256:

222 - x = 143

Next, isolate the variable "x" by moving the constant term to the other side of the equation:

-x = 143 - 222

Simplify further:

-x = -79

To solve for "x," we need to get rid of the negative sign. To do this, multiply both sides of the equation by -1:

x = -(-79)

x = 79

So, the value of the variable "x" is 79.
