Using the Distributive Property, 2(4n+1)=(2)(4n)+(2)(1)=8n2
and
5((25)n)88=5((25)n)+5(8)=2n40
Thus, the starting equation becomes 8n2+2n40=60
Simplify the LHS: 8n2+2n40=(8n+2n)+(240)=10n42
Thus (1) becomes 10n42=62
Add 42 to both sides and simplify: 10n42+42=62+42
10n42+42=62+42
Divide both sides by 10 and simplify: 10n10=2010 n=-2
