45-х=86-63

To solve the equation 45-х=86-63, we first simplify both sides separately.

45-х equals 45 minus x. And 86-63 equals 23.

So, the equation becomes: 45-x = 23

To solve for x, we need to isolate x on one side of the equation.

Let's move x to one side by subtracting 45 from both sides:

45 - x - 45 = 23 - 45

This simplifies to -x = -22

Now, to solve for x, we need to multiply both sides by -1 to get x by itself:

-x * (-1) = -22 * (-1)

This results in x = 22

Therefore, the solution to the equation 45-х=86-63 is x = 22.
