How I can solve this two equations... ?
Hi all ..
How I can solve this two equations to get a and w0 ... ? 12 .5 = W0 + 10a ====== 1 20 = 10W0 + 5a ======= 2 -------------- this my trying ... first I will multiply first equation with (-10) to remove the W0 then I will add both .. -125 = -10W0 - 100 a 20 = 10W0 + 5a -------------- -105 = -95 a a = 1.1 is that correct ... ? |

Either you can isolate a in one of them and insert a in the other to isolate W0.
Or you could substract 2 times the equation below from the above yielding: [itex] 12.5-40 = W_0 - 20W_0 +10a -10a [/itex] Then a should be easy(insert W0) |

Correct. Called Gaussian Elimination.
