<span>x + 3y = 5
2x - 3y = 1
------------------add
3x = 6
x = 2
</span>x + 3y = 5
2 + 3y = 5
3y = 3
y = 1
answer x = 2 y = 1

Answer:
we have 10 red marbles and 15 white marbles
Step-by-step explanation:
<u>Step 1:</u> Given data
Total marbles = 25
Ratio red: white = 2:3
<u>Step 2:</u> Write an equation
Red marbles = X
White marbles = Y
X+ Y = 25
X = 2/3 Y
2/3 Y + Y = 25
5/3 Y = 25
Y = 15
X =2/3 * 15 = 10
To control this we can plug this in the equation X + Y = 25
10 + 15 = 25
10/15 = 2/3
This means we have 10 red marbles and 15 white marbles
