Question

encontrar el valor de x en las siguientes ecuaciones: 2-1/2 (3-20x) + X/3= - 4(2x - 1 )

Answer 1

2 - 1/2(3 - 20x) + x/3 = -4(2x - 1)
2 - (3 - 20x)/2 + x/3 = -8x + 4
(4 - 3 - 20x)/2 + x/3 = -8x + 4
(1 - 20x)/2 + x/3 = -8x + 4
(3 - 60 + 2x)/6 = -8x + 4
-57 + 2x = -48x + 24
2x + 48x = 24 + 57
50x = 81
x = 1.62
