Question

Charles has 24 marbles. He has 6 hore yellow marbles than blue marbles. Which equation represents this situation?

Answer 1

see below

Explanation:

Let b = blue marbles

the number of yellow marbles = b+6

The total is 24

blue + yellow = 24

b+ (b+6) =24

2b+6 =24

Answer 2

2b + 6 = 24

Explanation:

Charles = 24 marbles in total

yellow = y

blue = b

He has 6 more yellow than blue marbles.

Write these scenarios as an equation

y + b = 24

y = b + 6

Substitute the value of y in the second equation into the first equation

b + 6 + b = 24

Add the b's together

2b + 6 = 24

Subtract 6 from both sides of the equation

2b = 18

Divide both sides of this equation by 2

b = 9

y = b + 6 = 9 + 6 = 15

He has 6 blue marbles, 15 yellow marbles, and the equation is 2b + 6 = 24

Hope this helps :)
