-10x + 5x = -5x
5x+5x-10 10x-10 is the only answer you can get from this
5x +12 = -78 -10x +10x +10x 15x +12 = -78 -12 -12 15x = -66 /15 /15 x = 4.4
x=-3
10x * 5x = 50x2 =====
-10x + 5x = -5x
(2x - 1)(5x + 8)
10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
That would depend on the plus or minus value of 2 which has not been given.
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3
5x(x - 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
5x + 4 = 10x - 5 10x - 5x = 4 + 5 5x = 9 x = 1.8
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
15x
5x+5x-10 10x-10 is the only answer you can get from this
5x + 8xy + 10x + 3xy = 15x + 11xycombine like terms (the x's and the xy's)
