Answer: n=58
Step-by-step explanation:
7(n-7)=3(2n+3)
We move all terms to the left:
7(n-7)-(3(2n+3))=0
We multiply parentheses
7n-(3(2n+3))-49=0
We calculate terms in parentheses: -(3(2n+3)), so:
3(2n+3)
We multiply parentheses
6n+9
Back to the equation:
-(6n+9)
We get rid of parentheses
7n-6n-9-49=0
We add all the numbers together, and all the variables
n-58=0
We move all terms containing n to the left, all other terms to the right
n=58
