Question

How many solutions does this system of equations have?

A; Exactly one.

B; Exactly two.

C; Infinitely many.

D; None.

Answer 1

c

Explanation:

Answer 2

Infinitely many solutions

Explanation:

make one equations to solve for y

2x + y= 1

-2x -2x

y= -2x+1

plug this in to the other equation

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

4x + -4x +2 = 2

4x + -4x cancels out

2= 2

this means there is infinitely many solutions
