It’s D bc Dt= 15x3 and it’s not that hard to solve
Answer:
4
Step-by-step explanation:
can also be written as 
. Evaluating this gives 
= 
= 
+5 and -5 because you root 25 which gives you + 5 or - 5
If you would like to solve y = x - 4 and 2 * x + y = 5, you can do this using the following steps:
y = x - 4
2 * x + y = 5
_____________
2 * x + (x - 4) = 5
2 * x + x = 5 + 4
3 * x = 9 /3
x = 9 / 3
x = 3
y = x - 4 = 3 - 4 = -1
The correct result would be x = 3 and y = -1.
