Answer:
3(x-5) =3x - x - 8
3x-15 = 2x - 8
3x-2x= -8+15
x=7
Explanation:
first 3 will multiply by x and -5,which are in bracet like this
3(x-5)= 3x - x -8
after they would became 3x-15 = 2x (because 3x will be subtracted by x) -8
so it will become like this
3x-15=2x-8
after that 3x will be subtracted by 2x like this 3x-2x and -8 will be add in +15 so it would be
x=7
