Question: - Solve the following set of simultaneous equations:

(x/5) + (2y/3) - (49/15) = 0
(3x/7) - (y/2) = -(5/7)
Using:
a) Substitution
b)Elimination.
Solution:-
a) By Substitution:-
Given equations are as follows:-

(x/5) + (2y/3) - (49/15) = 0 ------------------------------equation no.1
(3x/7) - (y/2) = - (5/7) ------------------------------equation no.2
Equation 1 can be written as:-
(x/5) + (2y/3) = (49/15)
Now let us find the value of x from above equation,
Subtract (2y/3) from both sides,
Therefore,
(x/5) + (2y/3) -...
