• (1,1)
• -2
• (1, 2)
• (1, -1)

What is the solution to the system?

• (0, 3)
• (1, -1)
• (-3, 1)
• (1, 3)

Solve for y:
2x + 2y = 6

• y = - x + 3
• y = x + 3
• y = 2x +6
• y = - 2x + 6

• (1, -4)

• (1, 4)

• (-4, -7)

• (-7, -4)

Solve the system of equations using the substitution method

• (3, 3)

• (1, 5)

• (1, 3)

• (7, -1)

7x + 4y = 12
