Answer:

Sofias solution is correct.

Step-by-step explanation:

First of all you do not need two sets of the same equation.

y=-1.5x + 5.7

y = 0.5x + 0.3

If you graph the y-intercepts first then graph the slope for the equation then you will get the right answer.

1) Graph 5.7 on the y-axis. | Then graph -1.5x going down on the y-axis and then go to the right on the x-axis.

Do the same for the other equation and you will get a solution of (2.7, 1.65) since they will intersect there.

$\\ \\ x \ \textless \ - \frac{4}{2} \ / \ simplify \\ \\ x \ \textless \ - 2 \ / \ simplify \\ \\ collect \ solutions \\ \\ x \ \textgreater \ 6 \ , \ x \ \textless \ -2 \\ \\$

So, your answer to this problem is x > 6 and x < -2.
