Explanation:
When we have variables on both sides we look for the coefficient that is lower than the two and reverse the sign.
Example:
1x+ 4 = 2x+3
We reverse 1x sign because it is lower so we will be subtracting
2x-1x = 1x
1x+3=4
We would then solve for x.

Let's begin to solve! </span>
Step 1:You would look for the coefficient or variable that is less and reverse the sign.
In this question the lower number is -x and so we would reverse the sign to add.
x+x= 2
Step 2: We now have
2x+3 = -5
Step 3: We will subtract 3 to -5 to find X
-3+-5= -8
Step 4:2x = -8
Divide both sides by two fo find x
Our answer:

-
Summary:
We first looked for the lower coefficient (in this case variable). We then flipped the sign and solved for x

Answer:
It is MOST LIKELY NOT going to land on green.
Step-by-step explanation:
Since the spinner has 6 sides, the total possible outcome is 6. There are 3 reds, 2 blues and 1 green.
The probability that the spinner will land on a green is
. But since we are looking for the probability that it won't land on green, we have 
From here we can best describe the likelihood that the spinner will land on a colour not green as: it is MOST LIKELY NOT going to land on green
The answer is B because the question states that the temperature at noon was 8 degrees below zero Celcius. 8 degrees below zero Celcius is written as -8 degrees.
