Hey there!!

3 ( x - 6 ) + 15 = 4 ( x - 1 ) + 4

3x - 18 + 15 = 4x - 4 + 4

3x - 3 = 4x

- 3 = x

x = -3

The mistake is , you have written -4 + 4 = 8

- 4 + 4 = 0

and - 18 + 15 = - 3 ( not - 33 )

correct it, you will get it

Hope helps!

in the second line on the distributive property is wrong it has to be

-3x+12=6x-9=12
