3(2x-5)-x=-7(x+3) Solve for x

I need help and the work also needs shown. THANKS IN ADVANCE!:3

6x-15-x = -7x-21

then...

5x-15 = -7x-21

then add 15 to both sides...

5x = -7x -6

then add 7x to both sides

12x = -6

divide 12 to both sides

x= NEGATIVE 1/2

6x - 15 -1x = -7x - 21
5x - 15 = -7x - 21
+7x +15= +7x +15
13x = 6
13x/13 = 6/13
x = 6/13 or x = 0.4615384

3(2x - 5)-x = -7(x+3)
6x - 15 -x = -7x - 21
6x - x + 7x = -21 + 15
12x = -6
X = -6/12
X= -1/2

6x - 15 - x = -7x -21
12x = - 6
x = -0.5
