Step-by-step explanation:
x+y=11 -------eq1
2x-3y=7 ---------eq2
So it can solve with three methods : Substitution method, Elimination method and cross multiplication method.
We solve this question in Substitution method.
x+y=11
x=11-y ------- eq3
2x-3y=7
putting eq3 in the eq2
2(11-y)-3y=7
22-2y-3y=7
22-5y=7
5y=15
y=3 -----eq4
x+y=11
putting eq4 in the equ1
x+3=11
x=11-3=8
Hence x=8 and y=3
