M+3/8m=1/41 3/8 m=1/4
m=1/4 : 1 3/8=1/4 * 8/11
m=2/11
y - 2/9 y=4 2/3
7/9 y=14/3
y=14/3 : 7/9=14/3 * 9/7
y=6
2/5 z+2/3 z - 7/15 z=2 1/2
(6/15+10/15 - 7/15)z=2 1/2
9/15 z=5/2
3/5 z=5/2
z=5/2 : 3/5=5/2 * 5/3
z=25/6=4 1/6
3 1/2 *(2/3 x+4/7)=2 1/3
2/3 x+4/7=7/3 : 7/2=7/3 * 2/7
2/3 x+4/7=2/3
2/3 x=2/3 - 4/7
2/3 x=14/21 - 12/21
2/3 x=2/21
x= 2/21 : 2/3=2/21 * 3/2
x=1/7
