When X = 4, 15X = 15 * X = 15 * 4 = 60
x-10=15 Add 10 to both sides x=25
If: 4x = x+15 Then: x = 5
If 15 + 3x = 42, then x = 9
X2 - 8X + 15 = (X - 3)(X - 5)
(15/100)x = 15 x = 15/(15/100) x = 15(100/15) x = 1500/15 x = 100
x+15 if you are trying to find the value of x it would be x+15 x=-15
find x+x+x when x=15 15+15+15=45
1 x 15 = 15 2 x 15 = 30 3 x 15 = 45 4 x 15 = 60 5 x 15 = 75 6 x 15 = 90 7 x 15 = 105 8 x 15 = 120 9 x 15 = 135 10 x 15 = 150 11 x 15 = 165 12 x 15 = 180 13 x 15 = 195 14 x 15 = 210 15 x 15 = 225
The absolute value of -15, written as |-15| = 15.
-15. Here's how. X-15=2X Subtract X from both sides. -15=X. There you have it. X=-15.
--x + 15 = x + 15
x+y=15 or y=x-15 x=-y+15 or you could graph and get (0,15) and (15,0) and thats it
154 = 15 x 15 x 15 x 15 = 50625
154 = 15 x 15 x 15 x 15 = 50625
x-9 = 15 x = 15+9 x = 24
-15 = x-3 x = -15+3 x = -12
