1. -3x=21
2. 13x=6
3. -12x=-7
answer the equation for points and brainiest.

1. x = -7

2. x = 6/13

3. x = 7/12

Step-by-step explanation:

1. x = 21 / -3

x = -7

2. 13x = 6

x = 6 / 13

x = 6/13

3. -12x = -7

x = -7 / -12

x = 7/12

Hope that helps!

1)---> 21 divided by -3 ---> x=-7

2)---> 6 divided by 13 ---> x=0.46 (rounded to the nearest tenth)

3)---> -7 divided by -12 ---> x=0.58 (rounded to the nearest tenth)

what is the original number? you forgot to add it.

86
