kropot72 · Answer

If you add 3x to both sides of the inequality we get:
y - 3x + 3x = 3x - 5
Can you simplify the left hand side?

y>3x-5

anonymous · Answer

you dont flip the sign or anything

kropot72 · Answer

You are correct. Sorry I left out the greater than symbol in my equation.

anonymous · Answer

so do you flip the sign to >< or keep it the same

kropot72 · Answer

No, you don't reverse the symbol in this case, the reason being we are not multiplying both sides by -1.

kropot72 · Answer

Does that make sense?

anonymous · Answer

What is the value of y when x = -3?

4x + 2y = 8
is it 2

kropot72 · Answer

Not really.
4x + 2y = 8
Plugging in x = -3 we get:
$$(4\times-3)+2y=8$$
Therefore
-12 + 2y = 8
Now can you add 12 to both sides? What do you get?
