Which equation is equivalent to n + 4 = 11?

• (n + 4) x 2 = 11

• (n + 4) x 2 = 11 + 2

• (n + 4) x 2 = 11 x 4

• (n + 4) x 2 = 11 x 2

If r + 9 = 42, does r + 9 - 9 = 42 + 9?

• Yes

• No

Answer explanation

The subtraction property of equality says you can subtract the same amount from both sides. In this equation, 9 was subtracted from the left side and 9 was added to the right side, so that would not be equal.

If 13 + 8 = 21, which property of equality is illustrated by the equation (13 + 8) + 2 = 21 + 2?
