You can put this solution on YOUR website!
3n/4 + 8 = -7

well since I hate fractions I will clear that first leaving you with

4(3n/4 + 8 = -7)
3n+32=-28

now subtract 32 from both sides

3n = -60

now divide both sides by 3

n = -20

3n/4 + 8 = -7
First of all subtract both sides by 8;
3n%2F4+8-8=-7-8
3n%2F4=-15
Now mnultiply each side by 4;
3n%2F4(4)=-15(4)
3n=-60
Nowdivide each side by 3;
3n%2F3=-60%2F3
n=-20
Hope you understand
