Question

1. which sum matches the statement "the sum of -4x and 2 is 9"?

Answer 1

1. "the sum of -4x and 2 is 9"? -4x + 2 = 9

Answer:
A.-4x + 2 = 9

2. solve x - 6 = -18
             x = -18 +6
             x = -12

Answer is B.x = -12

3. solve 4x + 3 = 47
             4x = 47 -3 
             4x = 44
               x = 44/44 = 11
Answer is A.x = 11

4. solve 1/3x = 12
                  x= 12 / (1/3)
                  x = 12 * 3 = 36

Answer is C.x = 36

5. solve 3x + 3 = 21
3x = 21 -3
3x  = 18
x = 18/3 = 6

Answer is B.x = 6

6. solve. 3/2x - 4 = 16
3/2x = 16 + 4
3/2x =20
x = 20 / (3/2)
x = 20 * 2/3
x = 40/3
A.x = 13 1/3

Answer is  B.x = 13 1/3
