5(x + 3)
Since 5x + 20 is a multiple of x + 4, it is automatically the LCD of this problem.
x2 - 5x + 6 = (x - 2)(x - 3)
x2+5x-14 = (x+7)(x-2) when factored
6x2 + 5x - 6 is factored out to (2x + 3)(3x - 2).
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x). Hope it helps :)
25x2+30x+9 25*9=225 15*15=225 15+15=3025x2+15x+15x+9[5*5xx 3*5x] [3*5x 3*3]5x(5x+3)+3(5x+3)(5x+3)(5x+3)Answer: (5x+3)2
5x+15 = 6x-10 5x-6x = -10-15 -x = -25 x = 25
5x+25=10 5x+25-25=10-25 5x=-15 5x/5=-15/5 x=-3
If you mean: 7x-3+5x+15 = 180 then the value of x works out as 14
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
if you meant 5x+9=3*15 then, 5x = 36, x = 7.2 if you meant 5x+9=3x+15 then, 2x = 6, x = 3
i don't know, why are you asking me? :)
5x + 15 = 28xSubtract 5x from each side:15 = 23xDivide each side by 23:15/23 = xThat's about 0.652 (rounded).
5x + 3 = -12 5x =-12-3 =-15 x = -3
x=4
