Summary:

Solve each system by graphing

Solve each system of linear equations by substitution.

1. Find the value of two numbers if their sum is 12 and their difference is 4.

2. The difference of two numbers is 3. Their sum is 13. Find the numbers.

3. The school that Stefan goes to is selling tickets to a choral performance. On the first day of ticket sales the school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. Find the price of a senior citizen ticket and the price of a child ticket.

10. 11.

Solve each system of linear equations by elimination.

1. A box contains 5 times as many dimes as nickels. The total amount in the box is $2.20. How many coins of each type are in the box?

2. In Ken’s pocket there are 3 times as many quarters as dimes. In all he has $1.70 in coins. How many coins of each type does he have?

3. There are twice as many nickels as pennies and 5 times as many dimes as pennies in Joan’s drawer. In all she has $1.22. How many coins of each type does she have?

4. Monica has three times as many nickels as pennies and twice as many quarters as nickels. In all she has $3.32. How many coins of each type does she have?

Solve each system.

5. Mitch put $4.55 in dimes and quarters on his desk. He has 7 more quarters than dimes. Find the number he has of each coin.

6. If Sue has $1.45 in nickels and dimes, and the number of dimes exceeds the number of nickels by 4, how many nickels and how many dimes does she have?

7. Constance has $2.80 in quarters and dimes. The number of quarters exceeds three times the number of dimes by 1. Find the number she has of each kind.

8. Wanda gave $5.30 in nickels, quarters, and dimes to her little daughter. The number of dimes exceeded the number of nickels by 3, and the number of quarters was 20 less than the number of nickels. Find the number of each kind of coin she gave to her daughter.

For each system, explain which method to use, then solve the system using that method.
