Frage 2
Frage
ECUACIONES =PASO a PASO= ...
=========================
2x² – 3 = 5 >>> x² = [blank_start]8[blank_end]/2 >>> x = [blank_start]2[blank_end]
2x / 3 + 3 = 7 >>> 2x = [blank_start]4[blank_end]·3 >>> x = [blank_start]6[blank_end]
x + 5 = 3x – 3 >>> [blank_start]8[blank_end] = 2x >>> x = [blank_start]4[blank_end]
x / 4 + 5 = 7 >>> x = [blank_start]2[blank_end]·4 >>> x = [blank_start]8[blank_end]
5 – ( x / 3 ) = 3 >>> [blank_start]2[blank_end] = x/3 >>> x = [blank_start]6[blank_end]
(x² – 1) / 5 = 3 >>> x² = [blank_start]16[blank_end] >>> x = [blank_start]4[blank_end]
