The correct answer is "<span>Step 2; 6x − 8 = 12 + 2x."
</span>
The step that the student first make an error is at the 2nd step. The correct step should be 6x − 8 = 12 + 2x.
Finishing the steps:
<span>Step 1: 2(3x − 4) = 8 + 2x + 4
</span>Step 2: <span>6x − 8 = 12 + 2x.
Step 3: 4x = 20
Step 4: x = 5</span>

Answer:
15x^2-14x-4
Step-by-step explanation:
(8x^2 * x-7x+2)+(7x^2 -7x-6)
you take out the parentheses
you add the common ones so -7x+-7x= -14x
8x^2 +7x^2 = 15x^2
and 2-6= -4
so in total it's 15x^2-14x-4
