Question

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.

Answer 1

x = 3 / 8

Answer 2

that isnt an option though

Answer 3

2x + y = 1
4x + 2y = −1
There is no x value as there is no solution.

Answer 4

what are the options then ?

Answer 5

it is either
1.x = 0

2. x = 2

3. There is no x value as there is no solution.

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

Answer 6

can you solve for "y" on the 1st equation? what would that give you?

Answer 7

it is 3 like I said.
