show me how to solve (the steps)

[(5 * x - 1) * 2 ] / 5 = 3     simplify

[(5x - 1 ) * 2] / 5  = 3    

(10x - 2) / 5  = 3       multiply by 5 on both sides

10x - 2  = 15             add 2 to both sides

10x = 17                   divide by 10 on both sides

x = 17/10

show me the steps in solving    $${\frac{{\left({\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{x}}{\mathtt{\,-\,}}{\mathtt{1}}\right)}^{{\mathtt{2}}}}{{\mathtt{5}}}} = {\mathtt{3}}$$
