X/3 + 48 = 3X X + 144 = 9X 8X = 144 X = 18 The number is 18.
6x + 18 = 4 - x 7x + 18 = 4 7x = -14 x = -2
If a number is added to itself, it is twice that number → 18 ÷ 2 = 9 → 9 + 9 = 18

It is simply: x+18 or 18+x
18+x=27 calculate and your answer should be 9.
X/3 + 48 = 3X X + 144 = 9X 8X = 144 X = 18 The number is 18.
6x + 18 = 4 - x 7x + 18 = 4 7x = -14 x = -2
9 x represents a number so in this equation it basically means what number is added to 9 to make 18 to work it out you do 18-9=9
If a number is added to itself, it is twice that number → 18 ÷ 2 = 9 → 9 + 9 = 18

2 x 3 x 3 = 18
5+x is 5 added to another number.
x+9=18 x = 9
no 4,913 = 17 x 17 x 17 = 17³ 5,832 = 18 x 18 x 18 = 18³
Let x = the number Equation: x = 18 + 1 Therefore, x=19
