Answer 1

$1)5x - 5 + 7 = 3x + 3 + 1 \ 5x - 3x = 3 + 1 + 5 - 7 \ 2x = 2 \ x = 2 div 2 \ x = 1 \ 2)2x + 2 + 3 = 3x - 3 + 6 \ 2x - 3x = - 3 + 6 - 2 - 3 \ - x = - 2 \ x = 2 \ 3)9x + 15 - 12x + 20 \ 9x - 12x + 15 + 20 \ - 3x = - 15 - 20 \ - 3x = - 35 \ x = frac{35}{3} \ 4)35 - 7x + 2 = 30 - 5x + 1 \ - 7x + 5x = 30 + 1 - 35 - 2 \ - 2x = - 6 \ x = - 6 div - 2 \ x = 3$
