Answer 2

Answer:

Let's replace the 17 with 12 and see the solution.

Step-by-step explanation:

3*2x + 5 = 14

adding -5 both sides we get,

3*2x +5 + (-5) = 14 + (-5)

3*2x = 9

We know that 9 = 3 x 3

3*2x = 3*2

since tha bases are equal, we ignore them and right their powers,

2x = 2

dividing both sides by 2 w get,

2x/2 = 2/2

.'., x = 1

That is if we replace 17 with 12.

If we take it the way it is with a 17, we will end up on

3*(2x-1) = 4 or 3*2x = 12.
