If you mean: -2x+8+20 then it can be simplified to 28-2x
12x - 2x = 10
If you mean: 4 = 2x then the value of x = 2
If you mean 2x-y = 8 then y = 2x-8
If you mean 2 times 2, then no, but 2 and 2x are monomials.
if you mean 2x-1*3 then the answer is: 2x-3
If you mean: -2x+8+20 then it can be simplified to 28-2x
12x - 2x = 10
2x+x is 3x
If you mean 2x+4(7x-1) then 2x+28x-4=30x-4=2(15x-2) If you mean 2x+4(7x)-1 then 2x+28x-1=30x-1
If you mean 2x times -2x then it would be -8x.
If you mean: 2x+10 then it is 2(x+5)
If you mean: 4 = 2x then the value of x = 2
If you mean x2 + 2x + 15: Then the answer would be that it's a quadratic expression with no factors. If you mean x2 - 2x + 15: Then it can be factored out to: (x - 5)(x + 3) If you mean x2 + 2x - 15: Then it can be factored out to: (x + 5)(x - 3)
If you mean 2x-y = 8 then y = 2x-8
If you mean 2 times 2, then no, but 2 and 2x are monomials.
If you mean: -2x = -4 then the value of x is 2
