Try and seelet try to put four unknown variable like a,b,c,d.
Then, then collect equations0 and solve them by using reduced row echelon form. Its so easy guys
3.5 + 4.5 = 8
+. +
9.5 + 3.5 = 6
=. =
13. 8
Kaka, nafikili upo wrong.
Izo alama za + (kujumlisha) zinatakiwa ziwe - (kutoa), angalia swali vizuri.
Mawazo yangu;
Formulate homogeneous system with four equations,
Collect it to get only two equations,
And final solve it. If your smart enough u will get non trivial solution e.g, x=2 also x=4 which implies that,
solution is not exist.
