A town's population is 14,000 and it is increasing by 160 people every year. A nearby town has a population of 24,000, and it is decreasing by 240 people every year.
After how many years will the populations of the towns be equal?
how do i write the equation to this?

In a certain pentagon, the interior angles are a, b,c, d,e where a, b,c, d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

For the equations below which statement is true ? -2x=14 6x=-42
