10x - 5x + 5x = 10x
-10x + 5x = -5x
10x ÷ 5x = 2
5x + 10x doesn't need factorization as you can just add them up (5x+10x=15x). However, if you really want to, 5x+10x=5x(1+2)=5x(3)=15x
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
you don't need to factor, just straight subtraction 5x-10x=-5x
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
1, 2, 5, 10, x, 2x, 5x, and 10x and the negative of each of those.
5x and 10x
5x+5x-10 10x-10 is the only answer you can get from this
10x - 18 = 5x + 2 Add -5x + 18 to both sides of the equation, to get: 5x = 20, from which x = 4.
