Answer:
z + 12 = 9
Reorder the terms:
12 + z = 9
Solving
12 + z = 9
Solving for variable 'z'.
Move all terms containing z to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + z = 9 + -12
Combine like terms: 12 + -12 = 0
0 + z = 9 + -12
z = 9 + -12
Combine like terms: 9 + -12 = -3
z = -3
Simplifying
z = -3

Answer and Step-by-step explanation:
We are told that AB is equal to 3x + 1.
BC is then half of AB, or
.
AC is then 4 less than BC, or 
To find the perimeter, we add all of these together.
3x + 3x/2 + 3x/2 = 6x
1 + 1/2 + (1/2 - 4) = -2
The final answer is 6x - 2.

Answer:
Step-by-step explanation:
3x - 6y = -1
-6y = -1 -3x
-6y = -(1+3x)
y = -(1+3x)/-6
y = (1 + 3x )/6
(1-52/2+5)=(1-26+5)=(-25+5)=-20
continuing:
-20*2*6*6= -40*6*6=-240*6=-1440
result: -1440
