Which value will replace the $x$ mark in the following equation?
$x-1586219=1903431$

The correct answer is
3489650

To find the value of \(x\) in the equation \(x - 1586219 = 1903431\), we will solve for \(x\) using basic algebraic manipulation.

  1. Start with the given equation:

\(x - 1586219 = 1903431\)

  1. To isolate \(x\), add 1586219 to both sides of the equation:

\(x - 1586219 + 1586219 = 1903431 + 1586219\)

This simplifies to:

\(x = 3489650\)

Therefore, the value that replaces the \(x\) mark in the equation is 3489650.

Let's confirm this answer by substituting it back into the original equation to verify:

  1. Substitute \(x = 3489650\) into the equation:

\(3489650 - 1586219 = 1903431\)

  1. Calculate the left-hand side:

\(1903431 = 1903431\)

The left-hand side equals the right-hand side, showing our solution is correct.

Thus, the correct answer is 3489650.
