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.
1) Put the x value on the same side of the equation
100= 160-10x+6x
100= 160-4x
2) put 160 on the other side of the equation
100-160=-4x
-60=-4x
3) divide -4 on both sides
-60/-4= -4x/-4
15=x
Hope this helps!
