63.5 divided by 5 is 12.7.
5x - 4 = -3x + 12.
move -3x to the other side
sign changes to +3x
5x+3x-4= -3x+3x+12
5x+3x-4= 12
move -4 to the other side
sign changes to +4
5x+3x-4+4= 12+4
8x= 16
divide by 8 for both sides
8x/8= 16/8
x= 2

Victoria can play 11 games. You'd usually round up, but in this case you can't play half a game so she'll play 11 games and have one quarter leftover.
The addition property of equality justifies this. You could also say that she simply subtracted 7, and then it would be the subtraction property of equality. This is the case because if you add or subtract (or multiply or divide) the same number on both sides of an equation, the equation will still be the same.
Hope it helps!
