At three hours as car a has already traveled a hour which making it three therefore making car b equal 2 hours or in a math equation 40×3=car b and 60×2=car a
X(5-8) would be the answer
You're solving for w for I assume.
P= -3w+9, put -3w on the left side and P on the right side.
3w= -P+9, divide both sides by 3.
w= -P+9 over 3.
w= -P over 3 plus 9 over 3.
(Final Answer):
w= -p over 3 plus 3.
Hope this helps.


We need the exact value of

to find a proper solution, but a general one can still be found. Subtracting the first equation from the second gives

Plug this into either equation and you get

(It's guaranteed that

in this case because that already corresponds to

.)
