What is the solution?

• (1, -1)
• (-1, 1)
• (0, -2)
• (2, 0)

Simplify each equation. Tell whether the equation has one, no, or infinite solutions.

3x - 7 = 3(x - 3) + 2

• one

• no solutions

• infinite solutions

Solve for y:
8x + 4y= 16

• y = -8x + 16
• y = 2x -4
• y = -2x + 4
• y = -8x + 12

n -10 +9n -3=

• -3
• 9n-3
• n
• 10n -13

3+4x+5x=21

• x=4
• x=-18
• x=2
• x=10

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

Simplify:
(x - 7)(x + 7)

• x² + 7x - 49
• x² - 7x + 49
• x² - 49
• x² + 49
