Answer

{$0$}

Work Step by Step

Step 1: $-4(2x-6)+8x=5x+24+x$ Step 2: $-8x+24+8x=6x+24$ Step 3: $-8x+8x+24=6x+24$ Step 4: $24=6x+24$ Step 6: Subtracting $24$ from both sides, $24-24=6x+24-24$ Step 7: $0=6x$ Step 8: $6x=0$ Step 9: Dividing both sides by $6$, $x=0$ Check: Step 1: Substituting the answer into the equation of Step 2: $-8(0)+24+8(0)=6(0)+24$ Step 2: Simplifying, $24=24$ Step 3: $0=0$ Since the result checks, the solution set of the equation is {$0$}.
