how do i solve this for example:| A=C+B
| B=F-D
{ C=D+E
| 20A+20B+4F=585
| 40C+5D-20B=0
| -5D+2E-4F=585
i've six equations and six variables.
how.
explain all details.
thankx in advance.

1st manner :
solve({a=c+b,b=f-d,c=d+e,20a+20b+4f=585,40c+5d-20b=0,-5d+2e-4f=585},{a,b,c,d,e,f})
in general : solve({equa1,equa2,...,equaX},{unknown1,unk2,...,unkX})
2nd manner :
activate the 2Dsymbol keypad, click on the "{" (above tje "lim")
you have :
{ O |
{ O | O
so you can enter a 2-equa 2-unk system
just click 4 more times on the "{", you have
{ O |
{ O |
{ O |
{ O |
{ O |
{ O | O
in the left O, type the equa
in the right down O, type a,b,c,d,e,f (the unknowns)
solve({a=c+b,b=f-d,c=d+e,20a+20b+4f=585,40c+5d-20b=0,-5d+2e-4f=585},{a,b,c,d,e,f})
in general : solve({equa1,equa2,...,equaX},{unknown1,unk2,...,unkX})
2nd manner :
activate the 2Dsymbol keypad, click on the "{" (above tje "lim")
you have :
{ O |
{ O | O
so you can enter a 2-equa 2-unk system
just click 4 more times on the "{", you have
{ O |
{ O |
{ O |
{ O |
{ O |
{ O | O
in the left O, type the equa
in the right down O, type a,b,c,d,e,f (the unknowns)
