This equation has no solution

Work Step by Step

$5-12x=8-7x-[6\div3(2+5^{3})+5x]$ Simplify the expression inside parentheses on the right side: $5-12x=8-7x-[6\div3(2+125)+5x]$ $5-12x=8-7x-[6\div3(127)+5x]$ Evaluate the division inside the brackets on the right side: $5-12x=8-7x-[2(127)+5x]$ Simplify the expression inside brackets on the right side: $5-12x=8-7x-[254+5x]$ Simplify the right side completely: $5-12x=8-7x-254-5x$ $5-12x=-12x-246$ The term $-12x$ is repeated on both sides. Cancel it: $5\ne-246$ False This equation has no solution
