What's the answer to this problem 19b-10=35b 22

19b-10=35b 22
Subtract 35b from 19b
-16b-10=22
Add 10 to both sides
-16b=32
Divide -16 on both sides so that the only thing remaining on the left side is the variable b.
Final b= -2

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
