Answer:
x=-1/2
Step-by-step explanation:
-6x-7=4x-2
-6x-7+6x=4x+6x-2
-7=10x-2
-7+2=10x-2+2
-5=10x
-5/10=10x/10
x=-1/2
Hope this helps!

<h3 /><h3>What is probability?</h3>
Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.
Given that:
Four usual dice are thrown
Total of numbers on the top faces of these four dice = 13
we know that in a dice, the sum of the numbers on any two opposite faces is always 7.
So,1 is opposite 6,
2 is opposite 5
and 3 is opposite 4.
Now, when 4,3,1 and 5 are the numbers on the top faces, then 3,4,6 and 2 respectively are the numbers on the face touching the ground as they sum upto 7.
Hence, total o faces touching the ground =3+4+6+2=15.
