I believe you set them equal to each other.
2x+4=5x-9
x=4.3
2(4.3)+4=12.6
I think the answer is 12.6
3r = 10 + 5s, where r = 10
Substitute 10 for r.
3(10) = 10 + 5s
30 = 10 + 5s
Subtract 10 from each side.
20 = 5s
Divide by 5.
4 = s
You need to work out the variables of 20 (the last number) first:
1, 2, 4, 5, 10, 20
Lets call these folks "p"
At that point you need to work out the components of the main coefficient (the number before the most astounding force of x):
1
Lets call this person "q"
At that point you need to make all the conceivable divisions you can with:
±p/q
Since q is only 1, we are fortunate, so the conceivable normal roots are:
±1/1,±2/1,±4/1,±5/1.±10/1,±20/1
Answer:
-20
Step-by-step explanation:
as you can see you can still see the 6s, whats the difference between 40 and 20? its 20, its like skip counting but negative, the answer couldve been "20" if it made the number go potitive but its negative so the answer is -20
