En resumen
C) - X + 20 = 31 - X = 31 - 20 - X = 11 D) - 6X - 30 = 6 - 6X = 6 + 30 - 6X = 36 X = 36÷6 X = 6 F) - X + 1 = 0 - X = 0 - 1 - X = - 1 lo demás no comprendo el asterisco ( * ).
C) - X + 20 = 31 - X = 31 - 20 - X = 11
D) - 6X - 30 = 6 - 6X = 6 + 30 - 6X = 36
X = 36÷6
X = 6
F) - X + 1 = 0 - X = 0 - 1 - X = - 1
