192 mugs per 6 layers.
Answer:
We need to solve each equation:
1. 2x - 5 = x
2x - x = 5
x = 5 ✅
2. -3b + 1 = 3b -5
5 + 1 = 3b + 3b
6 = 6b
b = 1 ✅
3. (1/2)t + 7 = (3/2)t - 4
t + 14 = 3t - 8
2t = 22
t = 11 ✅
4. -2.3 + 1.2x = 5.9 - 2.9x
2.9x + 1.2x = 5.9 + 2.3
4.1x = 8.2
x = 2 ✅
5. -7y -21 = -3y - 21
-21 + 21 = -3y + 7y
0 = 4y
y = 0 ✅
