This is a question mostly of order of operations. I solve from the center out:

2[4-2(3-x)]-1=4[2(4x-3)+7]-25

2[4-6+2x]-1=4[8x-6+7]-25

2(2x-2)-1=4(8x+1)-25

4x-4-1=24x+4-25

4x-5=24x-21 (add 21 to both sides)

4x+16=24x (subtract 4x from both sides)

16=20x (divide both sides by 20)

16/20=x (simplify)

3/4=x
