i also have another question

anonymous · Answer

look, you can isolate b on equation and substitute on f equation.

anonymous · Answer

As I remember in algebra, it would be *Equation F can be written as 5b + 1 = 3b + 4.*

anonymous · Answer

so you'll get b=(a-1)/5
substitute
a=3(a-1)/5+4

i still don't get it
