4(5x+5)=10(x-3)
20x + 20 = 10x - 30
20x - 10x = -30 - 20
10x = -50
x = -50/10
x = -5
-2(x-5)=3(2-4x)
-2x + 10 = 6 - 12x
12x - 2x = 6 - 10
10x = -4
x = -4/10
x = -2/5
4x÷3 - 3÷5 = 3x + 1÷2
4x/3 - 3/5 = 3x + 1/2
3x - 4x/3 = -3/5 - 1/2
9x/3 - 4x/3 = -6/10 - 5/10
5x/3 = -11/10
x = -11/10 * 3/5
x = -33/50
4x-3÷2 - 2x+5÷3 = 0
4x - 3/2 - 2x + 5/3 = 0
2x = 3/2 - 5/3
2x = 9/6 - 10/6
2x = -1/6
x = -1/6 / 2
x = -1/12
