Question

Solve the system of equations by substitution. What is the solution for x?

2x + y = 1
4x + 2y = −2

Answer 1

You have multiple choice?

Answer 2

yeah
x=0
x=2
x has no value so therefore ther is no solution
x is infinite number of solutions

Answer 3

but x does have a value right? I am confused
y=-x+0.5

Answer 4

Lets start off by isolating y
2x + y = 1
we use this because y is alone already which means less would :)
we subtract 2x from both sdies
y=-2x+1
now we use substituion :)
