1.03-0.62x=0.71-0.22x
Multiply thru by 100 to get rid of those pesky decimals:
103 - 62x = 71 - 22x
Subtract 71 from both sides to get:
32 -62x = -22x
Add 62x to both sides to get:
32 = 40x
Divide by 40 to get:
x = 32/40 = 4/5 or 0.8
-----------------------
The other two problems can be worked in the same way.
Good luck.
