3-6x=15 or,6x=3+15 or,6x=18 or,x=18/6 or,x=3 [Ans].
x = -1 Since -3(-1) + 15 = 18
If x-3x=18 then x equals -9
If the question is, What x 3 equals 15? Then 5 x 3 = 15 If the question is, What is 15 x 3? Then 15 x 3 = 45

10 x 15 x 18 x 40 x 15 x 3 is equal to 4,860,000.
3-6x=15 or,6x=3+15 or,6x=18 or,x=18/6 or,x=3 [Ans].
x = -1 Since -3(-1) + 15 = 18

X equals 10 XI equals 11 X11 equals 12 X111 equals 13 XIV equals 14 XV equals 15 XVI equals 16 XVII equals 17 XVIII equals 18 I = 1 V= 5 10 = X largest number first / lower numbers second 10 = x 11 = xi 12 = xii 13 = xiii 14 = xiiii 15 = xv 16 = xvi 17 = xvii 18 = xviii
If the question is, What x 3 equals 15? Then 5 x 3 = 15 If the question is, What is 15 x 3? Then 15 x 3 = 45
1 x 18 = 2 x 9 = 3 x 6 = 18
x=3 becaus: 6x=x+15 5x=15 (-x) x=3 (divided by 5)
x=5
3 + 3 = 6 6 x 3 = 18 18 - 3 = 15 15 + 3 = 18
