Question

1/2 = 5x+1/5 - 9-2x/4

Answer 1

1/2 = 5x+1/5 - 9-2x/4

1/2 = 20x+4 - 45-10x/20
20/2 = 10x-41
10 +41 =10x
51/10 =x = 5,1

Answer 2

1/2 = 5x + 1/5 - 9 - 2x/4
1/2 = ((10 (5x) + 2 - 5x - 10 * 9))/ 5 * 2
1/2 = (50x + 2 - 5x - 90)/ 2 * 5
1/2 = (45x - 88)/ 2 * 5
1/2 = (45x - 88)/10
10 (1) = 2 (45x - 88)
10 = 90x - 176
- 90x = - 176 - 10
- 90x = - 186
x = - 186/-90
x = 31/15

El valor de x es 31/15
