Answer:
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
Answer:
Solve the system of equations by substitution. What is the solution for x?
2x + y = 1
4x + 2y = −1
x = 0
x = 2
There is no x value, as there is no solution.
