$d + e = 2$ $d - e = 4$

Step 1

Subtract $e$ from both sides of the equation.

$d = 2 - e$

$d - e = 4$

Step 2

Replace all occurrences of $d$ with $2 - e$ in each equation.

Step 2.1

Replace all occurrences of $d$ in $d - e = 4$ with $2 - e$ .

$(2 - e) - e = 4$

$d = 2 - e$

Step 2.2

Simplify the left side.

Step 2.2.1

Subtract $e$ from $- e$ .

$2 - 2 e = 4$

$d = 2 - e$

$2 - 2 e = 4$

$d = 2 - e$

$2 - 2 e = 4$

$d = 2 - e$

Step 3

Since $2 - 2 e = 4$ is not true, there is no solution.
