4 x 15 + 9 = 69
That will depend on the plus or minus vallues of 15, 4, x and 9 which have not been given
(x + 4) + (x + 5) = 2x + 9
Find the solution for 4+6(X+9)
13/x+4=
13
24 24 + (-15) = 9
x + 5 + 4 = x + 9
If 15 + 3x = 42, then x = 9
Expressed as a formula, this is equal to (15 + 4)/x.
x=-9 15 + x = 6x + 60 x = 6x + 45 -5x = 45 x = -9 15 + (-9) = (6 * (-9)) + 60 15 - 9 = -54 + 60 6 = 60 - 54 6 = 6 There is no answer because, 15+x=6x+60 -15 -15 x=6x+45 Which is imposible because "x" can't equal itself times six plus forty-five.
x2+24x+144 = 9 x2+24x+144-9 = 0 x2+24x+135 = 0 (x+9)(x+15) = 0 x = -9 or x = -15
6x-x+15-9= 6x-x=5x 15-9=6 5x+6=0 5x=-6 x=-1.2
