1. Elige el procedimiento correcto para resolver la siguiente ecuación: 2(x – 3) = - (-x + 4)
A 2(x – 3) = -(-x + 4)
2x – 6 = x – 4
2x – x = -4 + 6
x = 2
B2(x – 3) = 1(-x + 4)
2x – 6 = -x – 4
2x + x = -4 + 6
3x = 2
x= 2
C 2(x – 3) = -(-x + 4)
2x – 6 = -x + 4
2x – x = 4 + 6
x = 10
D2(x – 3) = -(-x + 4)
2x – 3 = -x + 4
2x + x = 4 + 3
3x = 7
x= 7
