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

Rearrange the 2nd equation.

2x + y = 1

Subtract 2x to both sides:

y = -2x + 1

Plug in -2x + 1 for 'y' in the other equation.

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