1/2 (x-1) - 3/7 (x-5)= 2/7 please show me the steps to solve the answer is -19

Question

I need to be able to solve using the steps it took to get there, the answer being -19

Answer 1

(1/2)(x - 1) - (3/7)(x - 5) = 2/7
14[(1/2)(x - 1) - (3/7)(x - 5)] = 14(2/7)
14(1/2)(x - 1) - 14(3/7)(x - 5) = 4
7(x - 1) - 6(x - 5) = 4
7x - 7 - 6x + 30 = 4
x + 23 = 4
x = 4 - 23
x = -19

Answer 2

x/5 +9=4 can we solve the equation with steps on how to do it.
