Question

WICH OF THE FOLLOWING STATEMENTS ARE TRUE?
I. If y + 8 = -12, then y = -3
II. If 3y - 7 = -16, then y = -3
III. If 2x + 5 = 23 , then x = 9
IV. If 3x - 1 = 13, then x = 4

A. I and II
B. II and III
C. I and III
D. II, III and IV

Answer 1

Answer:

D. II, III and IV

If 3y - 7 = -16, then y = -3

If 2x + 5 = 23 , then x = 9

If 3x - 1 = 13, then x = 4

Answer 2

Answer:

$1. \: y + 8 = - 12 \\ y + 8 = - 12 \\ y = - 12 -8 \\ y = - 20$

$2. \: 3y - 7 = -16 \\ 3y = - 16 + 7 \\ 3y = - 9 \\ y = \frac{ - 9}{3} \\ y = -3$

$3. \: 2x + 5 = 23 \\ 2x = 23 - 5 \\ 2x = 18 \\ x = \frac{18}{2} \\ x = 9$

$4. \: 3x - 1 = 13 \\ 3x = 13 + 1 \\ 3x = 14 \\ x = \frac{14}{3} \\ x = 4.666$

B. 2 and 3
