7/8 of 18 = (7 x 18)/8 = 126/8 = 15.75 or 1/8 of 18 = 18/8 = 2.25 2.25 x 7 = 15.75
2.25 x 8 = 18

18 1 + 8 = 9 and 9 x 2 = 18

8 is twice as big as 4. 9 x 8 is twice as big as 9 x 4.
2(x+y) is twice the sum of x and y, and 2x+y is the sum of twice x and y
9 x 2 = 18 Therefore: twice
The expression "twice the difference of x and 5" would look like this: 2(x-5). To solve the problem, you would first subtract 5 from x, and then multiply the difference by two.
x + 10 = 18 18 - 10 = x 18 -10 = 8 x = 8
If: x+18 = 2x Then: x = 18
