Answer:3.219
Step-by-step explanation:
The equations classified according to the number of solutions are given as follows:
- No solution: -3(3q + 4) = -6q + 12
- One solution: -2(3n - 4) = -6n - 4
- Infinitely many solutions: 8z - 4 = 8z - 4
<h3>How many solutions does the equation 4(2z - 1) = 8z - 4 has?</h3>
We solve the equation, hence:
4(2z - 1) = 8z - 4
8z - 4 = 8z - 4
Equivalent, hence they have infinitely many solutions.
<h3>How many solutions does the equation -2(3n - 4) = -6n - 4 has?</h3>
-2(3n - 4) = -6n - 4
-6n + 8 = -6n - 4
0 = -12, which is false, hence it has no solutions.
<h3>How many solutions does the equation -3(3q + 4) = -6q - 12 has?</h3>
-3(3q + 4) = -6q + 12
-9q - 12 = -6q + 12
3q = -24
q = -8.
One solution.
