Step 1.1

Replace all occurrences of $y$ in $2 x + y = 2$ with $- 2 x - 1$ .

$2 x - 2 x - 1 = 2$

$y = - 2 x - 1$

Step 1.2

Step 1.2.1

Simplify $2 x - 2 x - 1$ .

Tap for more steps...

Step 1.2.1.1

Remove parentheses.

$2 x - 2 x - 1 = 2$

$y = - 2 x - 1$

Step 1.2.1.2

Subtract $2 x$ from $2 x$ .

$0 - 1 = 2$

$y = - 2 x - 1$

Step 1.2.1.3

Subtract $1$ from $0$ .

$- 1 = 2$

$y = - 2 x - 1$

$- 1 = 2$

$y = - 2 x - 1$

$- 1 = 2$

$y = - 2 x - 1$

$- 1 = 2$

$y = - 2 x - 1$

Step 2

Since $- 1 = 2$ is not true, there is no solution.

No solution
