Answer:

x = 3

Step-by-step explanation:

6x - 5 + 7x = 34

Find x

______________

To solve this, we need to isolate x :

First add like terms :

6x + 7x

13x

13x - 5 = 34

Add 5 to both sides :

13x = 39

Divide 13 from both sides to get x alone :

x = 3

In the first series, the summation applies to the whole (2n+3) inside
the parentheses, so the 3 gets summed up 5 times.

But in the second one, the summation only applies to the 2n , so
the 3 is only added after the summation is finished.

The difference between five 3s the first time and one 3 the second time
is your 12 .

Fantom [35]
You didn't give any choices, but the equation looks like this: 17 = 2x + 5.  Solving that for x tells you that he went on a big water slide 6 times. 2 times 6 plus 5 is the $17 he spent at the park.  See how well that works out?
