With two math 1. complete the following proof given: –x – 4 = 9 prove: x = –13 statements reason 1. –x – 4 = 9 1. given 2. –x = 13 2. 3. x = –13 3. division property of equality choices: addition property of equality, subtraction property of equality, multiplication property of equality, or division property of equality 2. complete the proof. given: ab = 7x + 1, bc = 4x, ac = 111 prove: x = 10 statement reason 1. ab = 7x + 1, bc = 4x, ac = 111 1. given 2. ac = ab + bc 2. 3. 111 = 7x + 1 + 4x 3. 4. 111 = 11x + 1 4. combine like terms 5. 110 = 11x 5. subtraction property of equality 6. 10 = x 6. division property of equality 7. x = 10 7. choices for 2, 3, and 7: picture below.
