Answer:
7:3
Step-by-step explanation:
The number of yellow marbles: the number of blue marbles
The incorrect answer is B.
All you have to do is plug in x to the formulas and see if the are equal.
4x - 2 = 3x + 6
4(8) - 2 = 3(8) + 6
30 = 30
CORRECT
The second is not only not equal, but it is the wrong kind of formula for what you are trying to prove there.
Hope that helps!
Multiply each number across from another
I hope this is the right answer and if it's not then my apologies.
And sorry it took so long.
