Explicación paso a paso:
[tex](x + 6) \times 3 + 24 = 15 \times 3 + x - 3 \\ 3x + 18 + 24 = 45 + x - 3 \\ 3x + 42 = 45 + x - 3 \\ 3x + 42 = 42 + x \\ - 42 + 42 = x - 3x \\ 0 = - 2x \\ x = 0 \\ \\ (0 + 6) \times 3 + 24 =15 \times 3 + 0- 3 \\ 6 \times 3 + 24 = 45 + ( - 3) \\ 18 + 24 = 45 - 3 \\ 42 = 42 \\ se \: cumple \: para \: x = 0[/tex]
espero te sirva
