Solve for n in the literal equation a(n-2)+5=bn

Helga [31]

Answer:

Answer is below

Step-by-step explanation:

a(n-2)+5=bn

Add -bn to both sides

an-2a+5+(-bn)=bn+(-bn)

an-bn-2a+5=0

add two a to both sides

an−bn−2a+5+(2a)=0+(2a)

an−bn+5=2a

Add -5 to both sides

an−bn+5+(-5)=2a+(-5)

an−bn=2a−5

Factor out our variable

n(a−b)=2a−5

Divide both sides by a-b

n(a-b)/a-b=2a-5/a-b

n=2a-5/a-b

Hope this helps

Postulates are helpful because it helps you plan and solve geometry problems.
That's my guess. It doesn't tell me in the text either.
