weird
OpenStudy (amistre64):
we dont just change operations ... we have to add or multiply or 'do the same thing' to both sides of the =sign
OpenStudy (amistre64):
+.99n has no y in it ... i call it a neighbor; send them back home; add -.99n to both sides
OpenStudy (amistre64):
48y, 48 is married to y (multiplication and marriage start with 'm') .. divorce the 48 ... divide both sides by 48
