Question

2x + y = 1
4x + 2y = −2

x = 0

x = 2

There is no x value as there is no solution.

x can be any value as there is an infinite number of solutions.

Answer 2

Solve the system of equations by substitution. What is the solution for x?

2x + y = 1......................(i)
4x + 2y = −1 ..................(ii)
Since we have to find x, there y should be eliminated, multiply (i) by 2
4x +2y = 2.....................(iii)
subtract (ii) from (iii)
0= 3 ,it cannot be possible
Hence there is no solution, because both are parallel..........................Ans

There is no x value as there is no solution.
