Answer:
number of yellow marbles=62.
Step-by-step explanation:
It is given that in a bag there are yellow marbles and blue marbles and the total number of marbles=73.
Let the number of Blue marbles=x, then according to the question, number of yellow marbles will be =5x+7.
Now, Total number of marbles= number of yellow marbles+number of blue marbles.
⇒73=x+5x+7
⇒73-7=6x
⇒66=6x
⇒x=11
Therefore, numberof blue marbles=x=11 and
number of yellow marbles=5x+7=5(11)+7=55+7=62.
