Answer: a-b+c+d =4
Step-by-step explanation:
The given system of equation is

from this we have the following matrices

the given matrix A =
On comparing Matrix
with Matrix A

we have the following values
a=2 ,b=4,c=8,d=-2
Thus a-b+c+d =2-4+8+(-2)=4
Answer:
THIS IS DA ANSWER OK LOLOLOL XD
If you would like to solve the equation - 2/5 * x + 6 = 8, you can do this using the following steps:
- 2/5 * x + 6 = 8
- 2/5 * x = 8 - 6
- 2/5 * x = 2 /*(-5/2)
x = 2 * (- 5/2)
x = - 5
The correct result would be -5.
$90.05•1055=95,002.75
so the answer would be B. 95,000
