(x+9)^2 =x^2 + 9 X^2 + 18x + 81 = X^2 +9 18X + 72 = 0 18X = -72 X =- 4
t-9=x
(92 x 2) - (9 x 2) = 162 - 18 = 144 The number is therefore 9.
x/4 - (9 - 3) =x/4 - 6
16
The number x is 5 more than 9
2x+9
If: 8+x = 17 Then: x = 9
x+9=18 x = 9
If X is the variable, then X/(-12+9) = x/(-3) = -X/3
6plus 9 equals x
0.5556
2X + 9 = Y or X = (Y - 9) / 2 where X is the number and Y is the result
(x + 9)
2X + 9 = Y or X = (Y - 9) / 2 where X is the number and Y is the result
9+(x/4)=12 x/4=3 x=12
set x = the compliment 90 = x + 9 + 2x = 3x +9 90 = 3x + 9 81 = 3x 27 = x = the compliment 90 - x = 63 degrees
