what is x in -5%281%2B2n%29=15...here you have variable n, not x
we can solve for n

-5%281%2B2n%29=15.....first multiply by -5
-5%2A1%2B%28-5%29%2A2n=15
-5-10n=15......add 10n to both sides

-5-10n%2B10n=15%2B10n
-5-cross%2810n%29%2Bcross%2810n%29=15%2B10n
-5=15%2B10n......add -15 to both sides
-5-15=15-15%2B10n
-5-15=cross%2815%29-cross%2815%29%2B10n
-20=10n
-20%2F10=n
highlight%28-2=n%29
