1.5(x+4)-3=4.5(x-2)
First, distribute 1.5 into x and 4, and 4.5 into x and -2, to get rid of the parentheses. Everything that we do to solve this equation is to isolate x to solve for its value.
1.5x+6-3=4.5x-9
Combine like terms on both sides (6-3).
1.5x+3=4.5x-9
Subtract 1.5x from both sides.
3=3x-9
Add 9 to both sides.
12=3x
Divide both sides by 3.
4=x
The answer is 4.

Answer:
an = 4n +5
Step-by-step explanation:
First we need to find a common difference
d = a2-a1 = 13-9 = 4
The formula for an
an =a1+d(n-1)
an = 9 + 4(n-1)
Distributing
an = 9+4n-4
Combine like terms
an = 4n +5
Answer:
-4 and -3
A negative times a negative results to a positive number, but when two negative numbers are added to each other, it still results to a negative number.
