Lets try and remove the brackets by multiplying the number with the bracket there.
-4(2x-5)=-8x+20
3(x-15)=3x-45
So now we have:
-8x+20 = 3x-45
Lets put the variables on one side and the numbers on the other side. Every variable or number that will change signs, will have their sign changed from a + into a - and vice versa.
3x+8x=20+45
11x=65
Divide both sides with 11.
11x/11 = 65/11
x=5.909
