Hello , just wanted to talk about solving equations fastly and precisely
i can't devolope a techinque !!!
Let's Have 2 Equations
5 = (v1-v2)/15 + v1/5
2 = (v2-v1)/15 +v2/4
7 = v1/5 + v2/4 => 140 = 4v1 + 5v2
5v2 = 140 - 4v1 => v2 = (140-4v1)/5
140 = 4v1 + 140-4v1 , 0=0 !!!!
!!! , how do i avoid this ?
please guide me to a good way of thinking to avoid all the traps .
i know that i'm noob , please help me .
