1.2x-7=1.3(x-12) how do you solve this equation

x = 86.

Step-by-step explanation:

Solve for x:

1.2 x - 7 = 1.3 (x - 12)

Expand out terms of the right hand side:

1.2 x - 7 = 1.3 x - 15.6

Subtract 1.3 x from both sides:

(1.2 x - 1.3 x) - 7 = (1.3 x - 1.3 x) - 15.6

1.2 x - 1.3 x = -0.1 x:

-0.1 x - 7 = (1.3 x - 1.3 x) - 15.6

1.3 x - 1.3 x = 0:

-0.1 x - 7 = -15.6

Add 7 to both sides:

(7 - 7) - 0.1 x = 7 - 15.6

7 - 7 = 0:

-0.1 x = 7 - 15.6

7 - 15.6 = -8.6:

-0.1 x = -8.6

Divide both sides of -0.1 x = -8.6 by -0.1:

(-0.1 x)/(-0.1) = (-8.6)/(-0.1)

(-0.1)/(-0.1) = 1:

x = (-8.6)/(-0.1)

(-8.6)/(-0.1) = 86.:

x = 86.

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.
