2(3x-4) = 5x+6
First, expand the bracket.
6x-8=5x+6
Next, move the variables to the same side.
x-8=6
Move the -8 to the other side, change to +
x=6+8
x=14
Charlie’s solution is incorrect. When expanding the bracket, he changed the - to a +.

Answer: 
Step-by-step explanation:
Given : The number of children in a family is 1, 2, 3, or 4.
Little Joe (a boy) has no brothers. But he may have sisters.
The sample space for the number of child in Joe's family : {B, BG, BGG, BGGG}, where G represents girl and B represents boys.
Then , for the probability that he is an only child, favorable outcome = B
Thus, the probability that he is an only child is given by :-

Hence, the probability that he is an only child =
