Answer:
n = -6
Step-by-step explanation:
10[6(n+1)+5(n-1)]=13[7(5+n)-(25-3)]
You will collect like terms
10(6n+6+5n-5)=13(35+7n-25+3)
it will give you this
10(11n+1)=13(10+10n)
Then you remove the parenthesis
110n+10 = 130 +130n
Move the terms
110n -130n = 130-10
collect like terms
-20n=120
divide both sides
n=-6
