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
