Answer 2

Let's solve the given equation step by step:

2(5x+2) - (2x-3) = 15

Distribute the 2 on the left side:

10x + 4 - 2x + 3 = 15

Combine like terms:

(10x - 2x) + (4 + 3) = 15

8x + 7 = 15

Now, subtract 7 from both sides:

8x = 15 - 7 8x = 8

Finally, divide both sides by 8:

x = 8 / 8 x = 1

So, the solution to the equation is x = 1.

Therefore, the correct answer is:
