  2. 4x + 3 = 47

  3. 1/3x = 12

  4. 3x + 3 = 21

  5. 3/2x - 4 = 16

Verified Answer :

The given equation is y = 3x - 1.

Test the given solutions.
A. (4,1)
y = 1
3x-1 = 34 - 1 = 11
Incorrect

B. (2,5)
y = 5
3x-1 = 32 - 1 = 5
Correct

C. (4,3)
y = 3
3x-1 = 34 - 1 =11
Incorrect

D. (0, -3)
y = 0
3x-1 = 30 - 1 = -1
Incorrect

Answer: B. (2,5)

1. x- 6 = -18
    Add 6  to each side.
    Answer: x = -12

2. 4x + 3 = 47
    Subtract 3 from each side.
    4x = 44
    Divide each side by 4.
    Answer: x = 11

3. 1/3x = 12
     Multiply each side by 3x.
     1 = 36x
     Divide each side by 36
     Answer:  x = 1/36

4. 3x + 3 = 21
    Subtract 3 from each side.
    3x = 18
    Divide each side by 3.
    Answer: x = 6

5. 3/2x - 4 = 16
    Add  4  to each side.
    3/2x = 20
    Multiply each side by 2x.
    3 = 40x
    Divide each side by 40.
    Answer  x = 3/40
