Answer:

there are 41 white marbles in the bag.

Explanation:

Let's use the variable w to represent the number of white marbles and y to represent the number of yellow marbles.

From the problem, we know that:

w + y = 49 (since there are 49 marbles in total)

And we also know that:

w = 5y + 1 (since the number of white marbles is 1 more than 5 times the number of yellow marbles)

Now we can use substitution to solve for w:

w + y = 49

(5y + 1) + y = 49 (substitute w = 5y + 1)

6y + 1 = 49 (combine like terms)

6y = 48 (subtract 1 from both sides)

y = 8 (divide both sides by 6)

Now we know there are 8 yellow marbles. We can use this information to find the number of white marbles:

w = 5y + 1

w = 5(8) + 1

w = 41
