Answer:
a(n-3)+8=bn
Step 1: Add -bn to both sides.
an−3a+8+−bn=bn+−bn
an−bn−3a+8=0
Step 2: Add 3a to both sides.
an−bn−3a+8+3a=0+3a
an−bn+8=3a
Step 3: Add -8 to both sides.
an−bn+8+−8=3a+−8
an−bn=3a−8
Step 4: Factor out variable n.
n(a−b)=3a−8
Step 5: Divide both sides by a-b.
n(a−b)
a−b
=3a−8/a−b
n=3a−8/a−b
Answer:
n=3a−8/a-b
