其實計li d數你首先應該搵下佢地有like terms....
有ge就將佢地simplify
(a) 5+b = 5+b
(b)-a+3 = 3-a
(c)c-4 = c-4
(d)a+3a = 4a
(e)5x+4x = 9x
(f)15y+9y = 24y
(g)23z-5z = 18z
(h)8x-6x = 2x
(i)176y-123y = 53y
(j)6a-16a = -10a
(k)8b-14b = -6b
(l)15b-15b = 0
(m)-5x-5x = -10x
(n)-12y-12y = -24y
(o)-77z-77z = -154z
(p)-13z-15z = -28z
(q)-2x+6x = 4x
(r)-16y+55y = 55y-16y = 39y
其實li d 數好易咋.....最緊要係留意正負號
