When working on equations such as this, try to isolate the unknown (or variable) on one side of the equation with all other terms being on the opposite side. If the coefficient of the unknown is not 1 then multiply or divide so that it is brought to 1.
5x - 4 = -6x + 3 : add 4 to both sides
5x = -6x + 7 : add 6x to both sides
11x = 7 : divide both sides by 11
x = 7/11

The answer is x = 2.
6x-2=x+135x=15x=3
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
2x+6x=-9 => 8x=-9=> x=-8/9
5x+3+x=24 6x+3=24 6x=21 x=3.5
