Hello teacher @khursheedanwar, I hope you are well, can you explain me how much is the X variable and the Y variable of this linear equation system that you explained in the post:
2x + 3y = 7
x - 2y = -3
Since among the different methods that you explained, none of the values that you found satisfy the equality, I got it by the elimination method and it gives me that X= 5/7 and Y= 13/7, if you substitute these values in the original equation if the equality is satisfied:
2x + 3y = 7
2(5/7) + 3(13/7) = 7
10/7 + 39/7 = 7
as it is a fraction with equal denominator, the numerators are added and the same denominator is placed, therefore:
49/7 = 7
7 = 7
if it is verified by the other equation it would be:
x - 2y = -3
5/7 -2(13/7) = -3
5/7 - 26/7 = -3
Since it is a subtraction of fractions of equal denominator, the numerators are subtracted and the same denominator is kept and the following is left:
-21/7 = -3
-3 = -3
Please clarify me the doubt to see if I am wrong, since for an equation to be well solved it has to satisfy the equality, that is to say that what is on the left side is equal to what is on the right side of the equality, that is to say that:
a= a
Hello @carlos84
I am sorry that I am responding you late and exactly for knowing that your answer is accurate or not you need to satisfy both sides of equations but first let me clear one thing to you;
You are writing that I have provided system of equations for solving as
But it's not true :-
True system of equation I provided is;
2x + 3y = 7
x - 2y = 3
Now you can solve it from elimination or substitution method anyone which is easy for you!
You will get true answer after solving it by using substitution or elimination method then ,which you can put in equation for satisfying both sides of equality for checking that your solution is accurate or not!
