prosze mi pomudz :
4=-2a+b
2=6a+b
prosze obliczyc a i b pilne na dzisiaj
I 4 = -2a + b
II 2 = 6a + b
I
4 = -2a + b
b = 4 + 2a
II
2 = 6a + b
2 = 6a + 4 + 2a
2 = 8a + 4
8a = -2
a = -2/8 = -1/4
b = 4 - 2/4 = 3 i 2/4 = 3 i 1/2
a = -1/4
b = 7/2
4+2a = b
2 = 6a+4+2a
b = 4+2a
2-4 = 8a
8a = -2 /:8
a = -2/8
b = 4+2·(-1/4)
b = 4-1/2
a = - 1/4
b = 3 1/2
