Question

If (2x − 1, y + 5) = (3, 10), the values of x and y are ______.

Options

• x = 4, y = 5

• x = 8, y = 5

• x = 2, y = 5

• x = 1, y = 5

Answer 1

If (2x − 1, y + 5) = (3, 10), the values of x and y are x = 2, y = 5.

Explanation:

Equating the corresponding coordinates from both sides of the ordered pair equation:

• 2x − 1 = 3
  2x = 4
  x = 2
• y + 5 = 10
  y = 5
