positive multiplied by positive = positive
negative multiplied by negative= positive
positive multiplied by negative (and vice versa) = negative
okay if x-4=3 then x=7 bcause 4+3=x = 4+3=7 and 7-4=3!
(x - 3)/(12 - 4x) = (x - 3)/[4(3 - x)] = (x - 3)/[-4(x - 3)] = 1/-4 = -(1/4)
3 x 2 x 4 = 24 (3 x 2) x 4 = 6 x 4 = 24 3 x (2 x 4) = 3 x 8 = 24 2 x (3 x 4) = 2 x 12 = 24
x=unknown number So the expression would be: 4(x+3) The sum of a number (x) and 3, all multiplied by 4.
You would write it as x/3 -4, where x is whatever the number is.
