Answer:
x = 35/36
Step-by-step explanation:
3(x-1/4) = 13/6 Distribute
3x-3/4=13/6 Add 3/4 on both sides
3x = 35/12 Divide by 3 on both sides
x = 35/36
11.45... to solve it, you add all of the numbers and then divide by the total number of numbers. so 126 divided by 11
-3x(-7) = -3(-2)(-7) ⇒ -42
-42 would be the answer.
The answer to your question is 9,9
