Ayuda con prueba porfavor 3 - 2x(5 - 2x) = 4x + x - 30 3[2x - (3x + 1)] = x + 1 3x - 7 = 2(x + 1) (X - 15) = 3(X - 19) 3(X + 4) = 4X - 1 2(3 - 4X) = 2X - 9 2(X + 2) = 4[2X - 5(X - 2)].
En resumen
3 - 2x(5 - 2x) = 4x + x - 30 3 - 10x + 4x = 4x + x - 30 - 10x + 4x - 4x - x = - 30 - 3 - 11x = - 33 <img src="https://tex.z-dn.net/?
3 - 2x(5 - 2x) = 4x + x - 30
3 - 10x + 4x = 4x + x - 30 - 10x + 4x - 4x - x = - 30 - 3 - 11x = - 33

13659. 07407, para comprobarlo multiplica esa cifra por 27 y listo.
A9 ese es el resultado.
