1.3n (it can be simplified like any other equation just add like terms and remember there is a one before every variable)
Answer:
A, C, E
Step-by-step explanation:
Welcome :)
Equivalent systems = same line = infinite solutions
P=2(L+W)
if length=7
and P=24
24=2(7+W)
divide both sdes by 2
12=7+W
minus 7both sides
5=W
width=5meters
