Z=7 all you really gotta do is subtract 12 from 19 and you get 7
Answer: x = 132 daw
Step-by-step explanation: believe me
(5x+7) + (8x-21) = 90
13x-14 = 90
13x= 104
X=8
The angle measurements are 47, and 43
Answer:
I think its -2/5 but not sure
Step-by-step explanation:
Steps to solve:
-4z + 4 + 12z = 3z + 4 + 5z
~Combine like terms
8z + 4 = 8z + 4
~Subtract 4 to both sides
8z = 8z
~Divide 8 to both sides
0 = 0
All real numbers are solutions.
Set builder notation: {x | R}
This is an identity since every value can be a solution to the equation.
Best of Luck!
