Question 1180014
.


I don't know which idea did you try to express or to present writing your equations in the post.


Surely,  it is  (or  "they are")  incorrect and irrelevant.



<pre>
The correct equations are


    10a + b = 4(a + b)

    10b + a = {{{(2/3)*(10a + b) + 52}}}.


Can you do the rest ?
