Explicație pas cu pas:
a)
3x/2 = 11/10 - 4/5 = 11/10 - 8/10 = 3/10
x = 3/10 : 3/2 = 3/10 *2/3 = 1/5
b)
4x/7 = 1/2 + 3/14 = 7/14 + 3/14 = 10/14 = 5/7
x = 5/7 : 4/7 = 5/7 * 7/4 = 5/4
c)
5x/6 = 3/2 - 1/3 = 9/6 - 2/6 = 7/6
x = 7/6 : 5/6 = 7/6 *6/5 = 7/5
d)
2x/5 = 22/15 - 4/3 = 22/15 - 20/15 = 2/15
x = 2/15 : 2/5 = 2/15 *5/2 = 1/3
e)
2x/3 = 4/8 - 11/24 = 12/24 - 11/24 = 1/24
x = 1/24 : 2/3 = 1/24*3/2 = 1/16
f)
5x/12 = 7/6 + 3/8 = 28/24 + 9/24 = 37/24
x = 37/24 : 5/12 = 37/24*12/5 = 37/10
