Answer:
-73
Step-by-step explanation:
substitue the -8 in for x. then multiply -8 by 7 you get -56. then subtract 17.
1) Seven million three hundred fifty thousand twenty-three
2) Two hundred thousand four hundred sixty-three
3) Twenty one million
i guess is by multiplying 3by the first equation and multiply 2by the second equation
8 - {x - (5 + x)}
= 8 - {x - 5 - x}
= 8 + 5
= 13
