Expand the brackets by multiplying everything in the brackets by -0.25.
-x x -0.25 = 0.25x
-12 x -0.25 = 3
0.25x + 3 = 2
-3 from both sides.
0.25x = -1
Divide both by 0.25
x = -4

Step-by-step explanation:
Step 1
The first step is to define the fundamental principle of counting. The fundamental principle of counting states that if a process can be carried out in n steps, where there are
ways to complete the first step,
ways to complete the second step,
, and
ways to complete the
step, this process can be carried out in
ways.
Step 2
We use the fundamental principle of counting with
for a total of
steps. This test can be carried out in
ways. This comes from multiplying 4 by itself 16 times.
