You should use your calculator for such simple sums. It is far quicker and involves fewer key depressions than posting the question on WA. But since you seem unable to carry out even this simple task, the answer is 270

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
If x-3x=18 then x equals -9

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)
3 + 3 = 6 6 x 3 = 18 18 - 3 = 15 15 + 3 = 18
x=5
