If 9x - 6y = 15 and x + 6y = 15, then the value of x,y.
Equation 1 : 9x - 6y = 15
Equation 2 : x + 6y = 15
Adding equations (i) and (ii), we get :
=> $$(9x+x)=(15+15)$$
=> $$10x=30$$
=> $$x=\frac{30}{10}=3$$
Substituting it in equation (ii), => $$6y=15-3=12$$
=> $$y=\frac{12}{6}=2$$
$$\therefore$$ $$(x,y)=(3,2)$$
