Answer:

The red one/bottom one. x>-8

Step-by-step explanation:

Subtract 7 giving you 16. Divide by negative 2 which gives you -8, but since your dividing by a negative you have to flip the sign. The Answer is x>-8. The Sign points which way you have to shade, the answer is which point you shade at, and the opened circle means that it is NOT equal to that answer but it is bigger. Closed circle if it is equal to. ;)

Solve 2x+y=7 for y what is y ?

masha68 [24]

You cant solve y but you can form an equation in terms of y
which is y=7-2x

if you were given another equation that has the term y and x than you can solve it.also that is a simultaneous equation.

Hope this helps,dont forget to put this as the brainliest answer if it does to help me out too. xD
