35x + 115 = 360 35x = 360-115 35x = 245 x = 245/35 x = 7
3/7x + 5 = 87x(3/7x + 5) = 8(7x)3(7x/7x) + (7x)(5) = 8(7x)3 + 35x = 56x3 + 35x - 35x = 56x - 35x3 = 21x3/21 = 21x/211/7 = x
42x+35x-35x=42x it's leave 85 so it's change into a negative 42x-85 is the answer
x3 + 2x2 - 35x = x(x + 7)(x - 5)

35x + 15x = 50x
35x + 115 = 360 35x = 360-115 35x = 245 x = 245/35 x = 7
3/7x + 5 = 87x(3/7x + 5) = 8(7x)3(7x/7x) + (7x)(5) = 8(7x)3 + 35x = 56x3 + 35x - 35x = 56x - 35x3 = 21x3/21 = 21x/211/7 = x
42x+35x-35x=42x it's leave 85 so it's change into a negative 42x-85 is the answer
35x*2=5x Well, I can only think of one way to solve this. Forgive if I'm wrong 'cause I'm only in 9th grade. I've tried it the other way where you solve the equation for zero, but it didn't work. So here's the only way I saw, I apologise if it is wrong. 35x*2=5x -5x......-5x 30x*2=0 .......-2-2 ..30x=-2 ...30x/30-2/30 x=-1/15
x3 + 2x2 - 35x = x(x + 7)(x - 5)
It is 35x.

52x - 14 - 35x = -133 First, combine like terms: (52 - 35)x - 14 = -133 17x - 14 = -133 Then, isolate the variable: 17x - 14 + 14 = -133 + 14 17x = -119 Finally, solve for x: (17x)/17 = -119/17 x = -7
25x + 35x + 9 is 60x + 9, which factors to 3(20x + 3)
