Answer:
Step-by-step explanation:
At the first place is better because
$0.8 * 5 = $ 4
$4.5 / 5 = $0.9
Is more expensive in the another place
Wen you deduct an amount from something
The equation given in the question is
3(3x - 1) + 2(3 - x) = 0
9x - 3 + 6 - 3x = 0
6x + 3 = 0
6x = - 3
x = - (3/6)
= - (1/2)
So the value of x as has been determined above is -1/2. I hope the procedure is clear enough for you to understand.<span>You can
