Answer:
Step-by-step explanation:
Solving by elimination and substitution:
x
+
y
=
7
x
−
y
=
−
3
on adding the two equations
y gets cancelled
x
+
y
=
7
x
−
y
=
−
3
2
x
=
4
x
=
4
2
=
2
substituting this value of x
in equation 1:
x
+y
=
7
2
+
y
=
7
y
=
7
−
2
y
=
5
the solution for the system of equations are :
x
=
2
y
=
5
