Answer:
x = 17.5
Step-by-step explanation:

To solve A =lw for l it means you want l on one side of the equals and anything not l on the other side. How are l and w put together? They are multiplied. We undo that multiplying with dividing.
A = l * w
A / w = l to divide both sides by w.
Thus l = A / w.
<span>3n-8+2(5n+3)=8n+5+4n first I will do the multiplication
3n-8+10n+6=8n+5+4n Now I will simplify
13n -2 = 12n +5 Now I will add 2 to both sides
13n = 12n + 7 then I subtract 12n from both sides
n = 7</span>
