Question

Solve the following system of equations:
x − 2y = 5
2x − 4y = 10

Answer 1

A) x − 2y = 5
B) 2x − 4y = 10

There is no solution.
The 2 equations are inconsistent.
Equation B is merely Equation A multiplied by 2.

Answer 2

x-2y=5
So x=5+2y
2x-4y=10
Putting the value of x
2(5+2y)-4y=10
10+4y-4y=10
10=10
So this system of eq.have infinitely very solutions
