7+x=15 x=8
If 40 plus x equals 25 then x is equal to -15.
X2 - 16X + 15 = 0 (X - 1)(X - 15) = 0 So X -1 = 0 or X - 15 = 0 ie X = 1 or X = 15
8x = 2x + 15 6x = 15 x = 15/6 = 2.5
15
find x+x+x when x=15 15+15+15=45
1over3x+x+x+8+x=15
The problem can be written as:46-3+7x-15 = 4243+7x-15=427x + (43-15) = 427x + 28 = 427x = 42 - 287x = 14x = 14/7 = 2
We cannot find out the y and x intercept for the equation 3x plus 5y equals -15 by a single equation . But , we can try a hit and trial method for the same . when x =0 y =-3. when y=0 x=-5.
15 x 6 or the long way is 90
15 + 15 x 6150 = 92265
x+5 = 3x+15 x-3x = 15-5 -2x = 10 x = -5
x² + 8x + 15 = (x + 5)(x + 3)
x + 3
x + 5
It can be simplified to: 3147+x
x+15+(-15)=6x+(15+(-15)=6x+(15-15)=6x+(0)=6x+0=6Add/subtract 0 from both sides,x=6
