4(x + 3) = 6 - x
First, expand to remove parentheses.
Second, subtract '6' from both sides.
Third, subtract '12 - 6' to get 6.
Fourth, subtract '4x' from both sides.
Fifth, since 'x' can be referred to as '1', add it to '4x' to get '-5x'.
Sixth, divide both sides by '-5'.
Seventh, change the whole fraction into a negative.
Eighth, switch your sides.

Answer:
Step-by-step explanation:
Total number of students in the class = 26
Number of boys in the class = 10
Number of girls in the class = 26 - 10 = 16
The formula for probability is :
In this case the favorable outcomes would be the number of girls in the class and total outcomes would be the total number of students in the class.
Eduardo has to pull out two names from the hat. Since there are 16 girls in the class of 26, the probability that the first name will be of the girl will be =
After picking up the 1st name, there would be 25 names in the hat with 15 names of girls as one of the girl is already been chosen. So,
The probability that the second name would belong to a girl =
The probability that both the partners will be girls will be equal to the product of two individual probabilities as both the events are independent.
Therefore,
The probability that both of Eduardo's partners for the group project will be girls =
