Systems of Equations

Solve the system of equations by elimination.

-x + y = -13

-8x - 4y = -8

Solve the system by substitution

3x + 2y = 16

7x + y = 19

Solve the system by graphing

8x + 4y = 12

y = -2x + 3

• (0,3)

• (3,0)

• No solution(parallel lines)

• Infinitely many solutions

Solve the system by elimination.

2x - y = 0

4x - y = 0

Solve the system by substitution

y = 2/3x - 2

y = -x + 3

Solve the following system by graphing

• Infinite number of solutions

• (3, 3)

• (3, -3)

• (-3, 3)

Solve the system by elimination

3x + 2y = 16

7x + y = 19
