Find the solutions of the form x=a,y=0 and x=0,y=b for the following pairs of equations.
Do they have any common such solutions?
i) 3x + 2y = 6 and 5x - 2y =10
(ii) 5x + 3y = 15 and 5x + 2y =10
(iii) 9x + 7y = 63 and x - y =10
please help :)

Answer:
Solve the following simultaneous equations. ... (2) x + 7y = 10; 3x – 2y = 7 ... Putting the value of y in (IV) we get 3x – 2 = 7 ⇒3x = 7 + 2 = 9 ⇒ 3x = 9 ⇒x = 3 ... (5) 3x – 4y = –7 ; 5x – 2y = 0

Answer:
as every variable is 0
i)3×0+2×0=6
0=6
simple answer is 6
5×0-2×0=10
0=10
=10
ii)5×0+3×0=15
0=15
=15
5×0-2×0=10
0=10
=10
iii)9×0+7×0=63
0=63
=63
0-0=10
0=10
=10
Step-by-step explanation:
when any number is multipled with 0 the answer is 0
