Salutare!

-10 = -2x => x = -10/-2 => x = 5

x/4 = -8 => x = -8/4 => x = -2

7 = x/3 => x = 7*3 => x = 21

-3x + 5 = -28 => -3x = -28 - 5 => -3x = -33 => x = -33/-3 => x = 11

6 + 12x = 150 => 12x = 150 - 6 => 12x = 144 => x = 144/12 => x = 12

-37 = -6x + 5 => -6x = -37 - 5 => -6x = -42 => x = -42/-6 => x = 7
