Answer:
The first pair shows equivalent expressions.
Step-by-step explanation:
3(x+2), you would have to distribute 3 among x and 2, also known as expanding the expression. So you'd do 3*x + 3*2, which equals 3x+6
The first equation is 3(x+2)=3x+6
Therefore, the first pair shows equivalent expressions.

Answer:
12
Step-by-step explanation:
I think you are trying to say
.
If that's the case, you can multiply the left side by 2/2:
10/12 = 10/x
Then, since the numerators are the same and the denominator of one side is 12, the denominator of the other side must also be 12. Therefore, x = 12.
I hope this helped.
