Solve for y y-x=11 x=17

$y - x = 11$ $x = 17$

Replace all occurrences of $x$ with $17$ in each equation.

Replace all occurrences of $x$ in $y - x = 11$ with $17$ .

$y - (17) = 11$

$x = 17$

Simplify the left side.

Multiply $- 1$ by $17$ .

$y - 17 = 11$

$x = 17$

$y - 17 = 11$

$x = 17$

$y - 17 = 11$

$x = 17$

The simplified system is the arbitrary solution of the original system of equations.

$y = 28$

$x = 17$
