Question

2. (04.02 LC) Solve the system of equations using substitution. (1 point) y = −2x + 1 4x + 2y = −1

Answer 1

No solution

Explanation:

`y=-2x+1`

`4x+2y=-1`

The first equation is set up in slope-intercept form but the second equation isn't. So first set up the second equation in slope-intercept form.

`4x+2y=-1`

Divide everything by 2

`2x+y=-(1)/(2)`

Solve for y

`y=-2x-(1)/(2)`

Both equations have the same slope but different y-intercepts which means that there is no solution
