The sum of 1/2 and 6 times a number is equal to 5/6 subtracted from 7 times the number

X =1/39

Step-by-step explanation:

1/2+ 6X = 5/6 - 7X Transposing terms

6X  + 7X =5/6 - 1/2

13X = 5/6 - 3/6

13X = 2/6 simplifying

13X = 1/3

and transposing 13:

X =1 / (13x3)  reducing

X= 1/39

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
