Question

2 (05.02)
Solve the system of equations by substitution. What is the solution for x? (1 point)
2x + y = 1
4x + 2y = -2
O x=0
o
There is no x value, as there is no solution
O
x can be any value, as there is an infinite number of solutions.
O x=2

Answer 1

Answer:

There is no $x$ value, as there is no solution.

Step-by-step explanation:

Given:

The equations are:

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

Divide the 2nd equation by 2. This gives,

$\frac{4x}{2}+\frac{2y}{2}=\frac{-2}{2}\\2x+y=-1$

Now, subtract equation 1 and 2.

$2x+y-2x-y=1-(-1)\\2x-2x+y-y=1+1\\0=2$

We are getting 0 equal to 2 which is not possible as 0 is less than 2. So, there is no solution for this pair of equations.

Answer 2

Answer:

There is no X value, as there is no solution.
