3(4x - 4) + 1/2(8x - 6) + 2x - 3 = -144
12x - 12 + 4x - 3 + 2x - 3 = -144
18x - 18 = -144
18x = -126
x = -126/18
x = -7 Answer
Its C
That answer would be 28 because 8 + 0= 8 and there is no number to add with the 2 so it stays the same making the 28

Answer:
$106,714.29
$71,142.86
$71,142.86
Step-by-step explanation:
There's a total of 7 pieces that they invested (3 + 2 + 2 = 7) so you can do 249,000 / 7 to find what each piece was worth.
249000/7 = about 35571.43
(you always have to round money to 2 decimal places)
Then the amount each brother spent would be:
3 * 35571.43 = 106714.29
2 * 35571.43 = 71142.86
2 * 35571.43 = 71142.86
