5 + 4x - 7 = 4x + 3 - x (eliminate alike terms in both sides)
5 - 7 = 3 - x (leave the variable alone by itself)
5 - 7 - 3 = 3 - 3 - x
-5 = -x (multiply both sides by -1)
5 = x

4x plus 7 plus 3x equals 19 plus xx = 2
No, that's not correct.-3x + 4x = x
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
-3x=-21+4x-3x-4x=-21+4x-4x-7x=-217x=217x/7=21/7x=3
4x+7-3x = 15 4x-3x = 15-7 x = 8
