Question

3 189-а = 1 068 + 129      

Answer 1

3189 - а = 1197
а = 1992

Answer 2

To solve the equation, let's simplify each side step by step:

3,189 - a = 1,068 + 129

First, we can simplify the right side of the equation:

1,068 + 129 = 1,197

Now we have:

3,189 - a = 1,197

To isolate the variable "a," we need to move the constant term (1,197) to the other side of the equation. We can do this by subtracting 1,197 from both sides:

3,189 - a - 1,197 = 1,197 - 1,197

Simplifying further:

1,992 - a = 0

To solve for "a," we need to isolate it on one side of the equation. We can do this by subtracting 1,992 from both sides:

1,992 - a - 1,992 = 0 - 1,992

Simplifying further:

-a = -1,992

To solve for "a," we need to multiply both sides by -1 to cancel out the negative sign:

(-1)(-a) = (-1)(-1,992)

Simplifying:

a = 1,992

Therefore, the solution to the equation 3,189 - a = 1,068 + 129 is a = 1,992.
