$y=9x-13$

Given: $" "18x-2y=26$
'..................................................................................................

Add $color(blue)(2y)$ to both sides

$color(brown)(18x-2ycolor(blue)(+2y)" "=" "26color(blue)(+2y))$

$18x+0" "=" "26+2y$

'................................................................................................

Subtract 26 from both sides

$color(brown)(18xcolor(blue)(-26)" "=" "26color(blue)(-26)+2y)$

$18x-26" "=" "2y$

'...........................................................................................

Divide both sides by $color(blue)(2)$

$color(brown)((18x-26)/color(blue)(2))" "=" "color(brown)(2y)/(color(blue)(2))$

$9x-13=y$

Write as:

$y=9x-13$
