4 + 10 - b + ( - 6) = b×( - 3) + 8?
4 + 10 - b + ( - 6) = b×( - 3) + 8.
4 + 10 - b + ( - 6) = b×( - 3) + 8.
En resumen
4 + 10 - b + ( - 6) = b * ( - 3) + 8 4 + 10 - 6 - b = - 3b + 8 4 + 10 - 6 - 8 = 3b + b 14 - 14 = 4b 0 = 4b 0 / 4 = b 0 = b.
4 + 10 - b + ( - 6) = b * ( - 3) + 8
4 + 10 - 6 - b = - 3b + 8
4 + 10 - 6 - 8 = 3b + b
14 - 14 = 4b
0 = 4b
0 / 4 = b
0 = b.
