7(4 - t) = -84
i got:
28 - 7t = -84
-28 = -28
7t = -112
----- -----
7 = 7
t = -16
is this right : -16
Here's your mistake:
7t = -112
It should be
-7t = -112
t = +16
oh ok i see thanks can you check another:
-5.5 (8+b) = -33
i got:
-44 + -5.5b = -33
+44 +44

Right!
Yes, your solution is correct. The value of t in the equation 7(4 - t) = -84 is indeed -16.
To get this solution, you followed the correct steps. Let me explain:
1. Start with the given equation: 7(4 - t) = -84.
2. Apply the distributive property: 7 multiplied by 4 is 28, and 7 multiplied by -t is -7t. So the equation becomes: 28 - 7t = -84.
3. Since we want to isolate the variable t, we need to get rid of the constant term (28) on the left side. To do this, subtract 28 from both sides of the equation: 28 - 28 - 7t = -84 - 28. This simplifies to -7t = -112.
4. To isolate the variable t, divide both sides of the equation by -7: -7t / -7 = -112 / -7. This simplifies to t = -16.
Therefore, the solution to the equation 7(4 - t) = -84 is t = -16, which matches your answer.
