If Marcos had 15 coins in nickels and quarters. He has three more quarters than nickels. Write a system of equations and solve t
Serhud [2]

Marcos has 6 nickels and 9 quarters

<em><u>Solution:</u></em>

Let "n" be the number of nickels

Let "q" be the number of quarters

<em><u>Marcos had 15 coins in nickels and quarters</u></em>

Therefore, we can say,

number of nickels + number of quarters = 15

n + q = 15 -------- eqn 1

<em><u>He has three more quarters than nickels</u></em>

Number of quarters = 3 + number of nickels

q = 3 + n -------- eqn 2

Eqn 1 and eqn 2 represents the system of equations

<em><u>Substitute eqn 2 in eqn 1</u></em>

n + 3 + n = 15

2n + 3 = 15

2n = 15 - 3

2n = 12

<h3>n = 6</h3>

<em><u>Substitute n = 6 in eqn 2</u></em>

q = 3 + 6

<h3>q = 9</h3>

Thus Marcos has 6 nickels and 9 quarters
