X -1÷8 = 20 then X equals

<span>x -1÷8 = 20 : x - 1 / 8 = 20 ( multiply both sides by 8 ) : x * 8 - 1/8 * 8 = 20 * 8 Refine: 8 x - 1 = 160 ( add 1 to both sides : ) 8 x - 1 + 1 = 160 + 1 8 x = 161 Divide both sides by 8 : 8 x /8 = 161/8 x = 161 / 8 decimal = 20.125 hope this helps! </span><span> </span>
First, multiply each side by 8 to get x-1=160, then add one to each side to get x=161. So, in conclusion, x=161! Hope this helped!
