Answer:
2x
Because 6 ÷ 3 = 2, so the answer is 2x
-24 because the negative is outside the absolute value
They are both equal because in decimals you can add thousands of zeros and it's still equal.
Plug in x = 12 and y = -5 into the given equation:-
3(12) - 3(-5) = 36 + 15 = 51 Not 21
So (12,-5) is not a solution.
$256.75
Add $178 + $98.25= $276.25
Then $276.25 - $19.50 = $256.75
