Why would you want a spoiler tag?
We already have a hide tag.

Means it's Mothers Day.
Phi day? 1[sup]st[/sup] of June, perhaps?

Remember that memorising the unit circle isn't necessary, the fact that it follows a clear pattern should make it easy enough to obtain the trigonometric values needed for the question.

1) Collect like terms;
12x = 96
Divide both sides by 12;
x = 96/12
x = 8
2) Subtract the two from both sides;
8z = 92
Divide both sides by 8;
z = 11.5
3) Divide 7 into 49 and you get 7, so;
w ≤ 7
So w is any value from negative infinity to 7

3y + 4x = 3y + 4x, you can't simplify that.
But if you were multiplying them, it would be;
4x × 3y = 12xy

Welcome.
I assume [X] means you have no knowledge at all on the subject?
If so, we can get you started. 
I hope you learn something useful during your time here at Maths Is Fun.

I've never really heard of any sort of formal celebration for the day of the natural logarithm, but I'd assume that it'd be on the 27th of January, or maybe the 7th of February.
