x=5
If: x/3 + 10 = 15 Then: x = 15
-15
If: x+10 = 25 Then: x = 15
x+5 = 3x+15 x-3x = 15-5 -2x = 10 x = -5
5x+15 = 6x-10 5x-6x = -10-15 -x = -25 x = 25
find x+x+x when x=15 15+15+15=45
If x equals 10 and y equals 10, then 9x plus 8y equals 170.
13x + 15 = 11x - 5 2x = -20 x = -10
1over3x+x+x+8+x=15
x = 13
The LCF is 45 because 15 x 3 equals 45 and 9 x 5 equals 45. Now, multiply 8 x 3 to get 24 and 2 x 5 equals 10. 24 plus 10 equals 34. The answer is 34 over 45.
