Answer :
Consider the given system of equation
x + 4y = 7
- 2x + 14 = 8y
Solution by elimination method :
From first equation 4y = 7 - x
Substitute 4y = 7 - x in second equation ,
- 2x + 14 = 2(7 - x)
- 2x + 14 = 14 - 2x
0 = 0
this implies that the equations are identical and hence there are infinitely many solutions
