Q:

Solve the system of equations by substitution. What is the solution for x?2x + y = 14x + 2y = -1Ox=0Ox= 2There is no x value, as there is no solution.x can be any value, as there is an infinite number of solutions.​

Accepted Solution

A:
Answer:There is no x value, as there is no solutionStep-by-step explanation:we have2x+y=1 Isolate the variable yy=-2x+1 -----> equation A4x+2y=-1 ---> equation BSolve the system of equations by substitutionSubstitute the equation A in the equation B and solve for x4x+2(-2x+1)=-14x-4x+2=-12=-1 ------> is not truethereforeThe system has no solutionEquation A and equation B are parallel lines with different y-intercepts
