Question

Solve the system of equations using substitution

y=-2x + 1
4x + 2y = -1

(0, -3)
(-3,0)
No solution
Infinitely many solution

Answer 1

No solution

Explanation:

choose which value to substitute

in this case y is easiest to substitute

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

4x-4x+2=-1

2=-1

this is a false statement, so there is no solution. If there was a solution, we would find out what x was and then substitute it in this first equation to find out what y was.

Answer 2

Answer: C. No Solution.

Step-by-step explanation: Solve for the first variable in one of the equations, the substitute the result into the other equation.
