Question

Solve the system of equations.
2a – b + c = -5

a – b = -2

2a + b = 5

Answer 1

a=1
b=3
c=-4

Answer 2

frm second equation
a=b-2
place the value of a in 2a+b=5
get the value of b as 3
and then a=b-2 frm 2nd
so a=3-2
now place the values of a n b in equation 1
and hence get the value of c finally :p
