x2 + 15x = 0x (x + 15) = 0x = 0x = -15
No. An equation must be equal to something, that's why its called an equation. 15x = 60 is an equation, in which case x equals 4
If you mean: y = -15x+60 then 15x+y = 60 When y = 0 then x = 4 When x = 0 then y = 60 Coordinates of the line are: (4, 0) and (0, 60)
90
This question does not make sense. If it should be X2 x 15X -54, the answer is: X2 -15X + 54 = (X - 6)(X -9)
When X = 4, 15X = 15 * X = 15 * 4 = 60

x2 + 15x = 0x (x + 15) = 0x = 0x = -15
Here is the answer with Steps: 15x - 18 = -2x - 5 15x = -2x + 13 17x = 13 x = 13/17 x ~ .764705882
X=-0.6
9x + 7 = 15x + 1 ___-1_______-1 9x + 6 = 15x -9x_____-9x ____6=6x ____/6_/6 ____1=x x equals 1.
15x = 45 Solve for x by dividing both sides by 15. 15/15 x = 45/15 Simplify. x = 3

5x2 + 15x = 0 5x(x + 3) = 0 therefore, x = 0 or x + 3 = 0 that is, x = 0 or x = -3
x is 12
The product of 15 and x is 15x. If you then want to substitute a numerical value for x to evaluate the expression of 15x when x equals that number then just multiply. For example, if x = 3, then 15x = 15(3) = 45 if x = 10, then 15x = 15(10) = 150 Good luck! :-)
x+15=16x=16-15x=1
