Răspuns :
5x + 1 = 8x + -5
1 + 5x = 8x + -5
1 + 5x = -5 + 8x
1 + 5x = -5 + 8x
1 + 5x + -8x = -5 + 8x + -8x
5x + -8x = -3x 1 + -3x = -5 + 8x + -8x
8x + -8x = 0 1 + -3x = -5 + 0 1 + -3x = -5
1 + -1 + -3x = -5 + -1
1 + -1 = 0 0 + -3x = -5 + -1 -3x = -5 + -1
-5 + -1 = -6 -3x = -6
x = 2
Sper ca te-am ajutat :*
