Question

Which equation has the solution x = 3?

Select each correct answer
09 - 31 = 0
0 +5=6
2x + 4 = 10
09-1=4
51 - 7 = 1
3x + 1 = 9

Answer 1

2x + 4 = 10 = x =3

Explanation:

09 - 31 = 0 (the variable x is not present in the given system)

0 +5=6 (the variable x is not present in the given system)

2x + 4 = 10 = x = 3

09-1=4 (the variable x is not present in the given system)

51 - 7 = 1 (the variable x is not present in the given system)

3x + 1 = 9 = x = 8/3
