The value of x is 42. Multiply the top and bottom by 6 because the numerator in the first fraction is 2 and the numerator for the second fraction is 12. When you multiply 2 by 6, you get 12. You have to do the same for the denominator. multiply 7 by 6. You get 42. The value of x is equal to 42. Hope this helps.
Answer:
42
Explanation:
First, you cross multiply.
12 x 7= 84
2 multiplied by x will give you 2x.
Now, you have the equation below left:
84=2x
Then, you divide by 2 on both sides (in order to leave x by itself):
84/2= 42
x=42
