Abag contains yellow marbles and red marbles, 65 in total. the number of yellow marbles is 5 more than 4 times the number of red marbles. how many yellow marbles are there?

16

Step-by-step explanation:

53

Step-by-step explanation:

You make formulas for it.

Y= yellow marble and r= red marbles

So we know y+r=65

and y=5+4r because there are 5 more (plus) and 4 times ( multiply) yellow marbles

so now we make y+r=65 to have r= so you subract to the y so you get r= 65-y

now you plug that into your other formula

y= 5+ 4(65-y)

distribute

y=5+ 260-4y

add common numbers

y=265-4y

add 4y from both sides

5y=265 ( it is 5y because there is already a 1y on that side and 1y+4y=5y

then divied both sides by 5      y=53

2/3
