Answer:
Z=16
Step-by-step explanation:
just add 12 to both sides so you are left with only Z on one side
=16
Simplifying
z + -12 = 4
Reorder the terms:
-12 + z = 4
Solving
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 = 4 + 12
Combine like terms: -12 + 12 = 0
0 + z = 4 + 12
z = 4 + 12
Combine like terms: 4 + 12 = 16
z = 16
Below is an attachment containing the solution.
Answer: Move terms to the left side−52+3=−9−5x2+3x=−9−52+3−(−9)=0−
Common factor−52+3+9=0−5x2+3x+9=0−(52−3−9)=0
Divide both sides by the same factor−(52−3−9)=0−(5x2−3x−9)=052−3−9=0
Solution=3±321 over 10
A came to C, C was supposed to go to A
