To find " X", you'll need subsitute "y" with 15 and solve the equation. So, it would look like this: x - y = 30 x - 15 = 30 (subsitute) x - 15 + 15 = 30 + 15 (add on both sides of the = sign) x = 45 (final solution) Hope this helps! :)

[latex]x-y=30 \ when \ y=15 \\ \\ x-15=30 \\ \\ x=30+15 \\ \\ x=45[/latex]
