The expression is 15x + 1732.
7
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
find x+x+x when x=15 15+15+15=45
1over3x+x+x+8+x=15
--x + 15 = x + 15
2x - 1 = x + 15 Add 1 to both sides: 2x = x + 16 Subtract x from both sides: x = 16
15 x 6 or the long way is 90
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 + 15 x 6150 = 92265
x+5 = 3x+15 x-3x = 15-5 -2x = 10 x = -5
Without parentheses, it's hard to tell which was the original problem, so here are both solutions: (x/5) + 8 = 15 x/5 = 7 x = 35 OR x/(5+8) = 15 x/13 = 15 x = 195
x² + 8x + 15 = (x + 5)(x + 3)
