Well there are a few ways to "read" the question you wrote...
What is the answer to 0.5 times 'x' and then add 'x' to that answer
0.5(x) + x = ?
or
What I think is being looked for is this: What is x + x and that answer multiplied by 0.5
Therefore, what is the answer to 0.5(x + x) = ?
I think the question is the second equation.
To answer this equation, you would multiply 0.5 to x, then multiply 0.5 to the other x, equaling 0.5x + 0.5x. Then add the two together (0.5x + 0.5x) and you get 1.0x or just 'x'
Therefore, 0.5(x +x) = 1x or "x"
x+4x+5 = 0 5x + 5 = 0 5x = -5 x = -1
5(x + y)
It is (x+5)(x+1) when factored
x squared +6x +5 is a quadratic expression that can be factored as (x+1)(x+5)
if 3x+5=x+19 then x=7
x+4x+5 = 0 5x + 5 = 0 5x = -5 x = -1
5 + 5 + 5 + 5 X 5 = 100
5 x (5 + 9) x 9 = 5 x 14 x 9 = 630
The letter X times 1 times 5 times 11 times 5 equals 25. You will first have to find the value of the letter X.
6 x 8 + 9 x 5 = 285
Say x is 5 so 5 + 5 = 10 where as 5 times 5 = 25 The difference is "x + x" is a addition and "xx" (x times x) is a multiplication.
If you mean: 2x+5+3x = 25 then the value of x works out as 4
5(x + y)
No. It simplifies to a monomial.
