M=f+240

m+f=25000, using m from above in this equation gives you:

f+240+f=25000  combine like terms on left side

2f+240=25000  subtract 240 from both sides

2f=24760  divide both sides by 2

f=12380, and since m=f+240

m=12620

So there are 12620 males and 12380 females in the city.

To solve you start by dividing 25,000 in half. This gives you 12,500. Then you subtract 240 from it to find the number of females (12,260). Finally you subtract 12, 260 from 25,000 to find the number of males.

So there are 12,260 females and 12,740 males

In order to find this you have to set i by itself first we will subtravt 40 from both sides(because 40 is s positive and in order to get rid of a positive you have to use a negative) now we have -40=5i, now divide 5 from both sides to get i=-8, that is what Terry will be givng from tip

Hope this helps
