You can work this out simply. First, simplify the problem:
-7 = 3t + 2
... Cancel out the +2.... (by subtracting 2 from each side....)
-7 -2 = 3t + 2 -2
----------------------
-9 = 3t
Now that you have a whole number on one side, and your equation on the other... divide both sides by 3 to figure out what "t" is
-9 / 3 = 3t / 3
------------------------------
-3 = t
Simple, right? ;D

If 2t plus 3 equals -9 what is the value of -3t-7?
2t + 3 = -9Subtract 3 from each side:2t = -12Divide each side by 2:t = -6======================-3t - 7 = (-3)(-6) - 7 = +18 - 7= 11.
How do you simplify 7 plus t-3t?
4
2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 8 plus 4 equals 96 Then 9 plus 7 equals?
If I am correct, 9 plus 7 equals 112.
-5t plus 9 plus 2t equals 30?
-5t + 9 + 2t = 30Combine like terms on the left side:-3t + 9 = 30Multiply both sides by -1"3t - 9 = -30Add 9 to both sides:3t = -21Divide both sides by 3:t = -7
9t squared plus 42t plus 49?
9t2 + 42t + 49 is a perfect square, equal to (3t + 7)2
