Ayuda por favor - 2( - x - 1) = 5 + 1 - 2 - x + 4( - 2x - 3) = - 8x + 1 6x = - 4 + x + 3 + 1 4(x - 3) - 5(x + 2) = 7(3x - 1) + 29 [tex] \ frac{x - 2}{ - 2} = 6[ / tex] [tex] \ frac{ - 5 - x}{ - 3} = - 2[ / tex].
En resumen
A_ - 2( - x - 1) = 5 + 1.
A_ - 2( - x - 1) = 5 + 1.
2x + 2 = 6 2x = 6 - 2 2x = 4 X = 4÷2 X = 2B_ - 2 - x + 4( - 2x - 3) = - 8x + 1 - 2 - x - 8x - 12 = - 8x + 1 - 2 - x - 12 = 1 - 14 - x = 1 - x = 1 + 14 - x = 15 X = - 15C_ 6x = - 4 + x + 3 + 1 6x = 0 + x 6x = x 6x - x = 0 5x = 0 X = 0÷5 X = 0D_ 4(x - 3) - 5(x + 2) = 7(3x - 1) + 29 4x - 12 - 5x - 10 = 21x - 7 + 29 - x - 22 = 21x + 22 - x - 21x = 22 + 22 - 22x = 44 X = 44÷( - 22) X = - 2.
Es primero multiplicas luego divides y luego sumas.
