3 ( x - 3 ) = 5x - 4 + 3 ( 7 - x ) x = ?
i tried working it out and got 21 but the answer was 26 , how do you show your workings

26

Step-by-step explanation:

3 ( x - 3 ) = 5x - 4 + 3 ( 7 - x )

3x-9 = 5x-4 + 21 - 3x

collect like terms

3x-9 = 2x +17

move the terms

3x-2x = 17+9

x=26

26

Step-by-step explanation:

3 (x-3) = 5x - 4 + 3 (7-x)

3x - 9 = 5x - 4 + 21 - 3x

3x - 9 = 5x - 3x + 17

3x - 9 = 2x + 17

3x - 2x = 17 + 9

x = 26

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.
