1 answer:
Since we know an isosceles triangle has 2 congruent sides we can know that the both equations can be set up as 
. First, We combine like terms 
. The new equation is 
. We do the inverse operation of subtracting 3 which is adding 3, we add 3 to both sides of the equation. The equation is now simplified as 
because we added 3 to both of the sides. Finally, we do the inverse operation of multiplying by the known coefficient of 2y which is 2, we end up dividing both sides by 2 which ends up with the equation y=6. Thus, we can conclude that y is the length of x and y which is also equal to 3.

<u>Answer:</u>
Annual Income of A=
and
Annual Income of B=
<u>Step-by-step explanation:</u>
<u>Given Data:</u>
Ratio of annual income of A and B=4:3
Ratio of expenditures of A and B=3:2
Saving of A and B=1000
<u>Required:</u> Annual Income of A and B=?
<u>Solution:</u>
If ratio of income of A and B is 4:3
then let Income of A= and Income of B=
If ratio of expenditure of A and B is 3:2
then let expenditure of A= and expenditure of B=
Therefore,
...........
and ..........
subtracting Eq(1) and Eq(2), we get
putting in Eq(1), we get value of
as
because x and y are equal in Eq (3)
Now, Annual Income of A=
and Annual Income of B=
