Combine like terms.
2x+20=3x-5
20=3x-5-2x
20+5=3x-2x
25=x
Answer:
19. (-∞,-5)U(-5,2)U(2,∞)
20. (-∞,-6)U(-6,4)U(4,∞)
21. (-∞,10)U(-10,3)U(3,7)U(7,∞)
Step-by-step explanation:
To summarize these three equations, ignore the numerators for every three equations listed, flip the + and - for each side to get the x values. You have to put the values from smallest to largest in order to state the domain. You need this sign -> U for the answers.
Answer:
Assuming you're solving for <em>n</em>, 1. n=-1 2. n=-1.6
Step-by-step explanation:
1. -5(2-5n)+6=-5n-34-2
Distributive Property
-10+25n+6=-5n-32-2
Add Like Terms
-4+25n=-5n-34
Subtract -4
25n=-5n-30
Subtract -5n
30n=-30
Divide by 30
n=-1
2. -5(2-5n)+6=-5n-34-20
Distributive Property
-10+25n+6=-5n-32-20
Add Like Terms
-4+25n=-5n-52
Subtract -4
25n=-5n-48
Subtract -5n
30n=-48
Divide by 30
n=-1.6
