Simplify a-{3a-[4a-(2a-4a)]}

Mathematics
1 answer:
Dvinal [7]3 years ago

Start from the inside and work your way out.
we would start with simplifying (2a-4a) first, giving us (-2a) instead of the previous.
(4a-(-2a)) would give us a positive 6a.
(3a-6a) would give us a (-3a)
a-(-3a) would leave us with a simplified 4a.
that's the answer, hope that helped!! xx

Ksju [112]

Answer:

17. xy + z = 51

18 yz - x = 18

21. 5z + ( y - x ) = 20

22. 5x - ( y2 - 4x ) = -10

23 . x2 + y2 - 10z = 70

24. z3 + ( y2 - 4x ) = 1

25. y + xz / 2

26 .3y + x2 / z = 30

Step-by-step explanation:

17.(6 x 8)+3=

    48+3=51

18.(8 x 3)- 6 =

     24 - 6 = 18

21. 15 + ( 8 - 3 )

      15 + 5=

        20

22 .30 - (64 - 24)=

      30 - 40=

       -10

23. 36 + 64 - 30

      100 - 30

        70

24.  9 + (16 - 24 )=

       9 + -8 =

        1

25. 8 + 48 / 2

      56 / 2

       28

26. 24+ 36/3

      60/3=

       30
