Solve the system of equations by substitution. what is the solution for x?
2x + y = 1
4x + 2y = -1
ox=0
ox= 2
there is no x value, as there is no solution.
x can be any value, as there is an infinite number of solutions.

There is no x value, as there is no solution

Step-by-step explanation:

we have

2x+y=1

Isolate the variable y

y=-2x+1 > equation A

4x+2y=-1 ---> equation B

Solve the system of equations by substitution

Substitute the equation A in the equation B and solve for x

4x+2(-2x+1)=-1

4x-4x+2=-1

2=-1 > is not true

therefore

The system has no solution

Equation A and equation B are parallel lines with different y-intercepts
