To solve the expression (2X \times 50), we need to find a value for (X) that makes sense contextually, but it seems like there is a misunderstanding in the expression. If we assume you want to simplify it, you can replace (X) with any number, and the expression will yield a result. For instance, if (X = 1), then (2 \times 1 \times 50 = 100). If you meant to set the expression equal to a specific number, please clarify for more precise assistance.
1/2x+6=1/3x 3x+36=2x 3x=2x-36 x=-36
It depends on the value of x. The x is a variable. To evaluate an expression, you need to have a value (number) to replace the x.
9+4x=2x-1 2x=-10 x=-5
It is equal to 2x because if you were to replace the "x" with a number say, 2 for example so 2 + 2 would be 4 and 2 times 2 would also be 4 which is what "2x" stands for (2 times x). So then if you had x + x you would get 2x.
Let x = one number. x + 10 is the other one. 2x + 10 = 40 2x = 30 x = 15 x + 10 = 25 15 + 25 = 40

eigthy one plus a number
2x - 5 = 1Add 5 to each side:2x = 6Divide each side by 2:x = 3

X = 7 9x - 2x = 49
The Answer:You are implying that 2x - 9 = 31. Add 9:2x = 40Divide by 2:x = 20Therefore, the number must be 20.
Let 'x' represent "the number": 2x - 7 = -147 Solving: 2x = -140 x = -70
Let the number be x 12-2x = -7 -2x = -7-12 -2x = -19 x = 9.5
The answer to your question is (2x + 2y)^-1 = 1/(2x + 2y)^1. When you raise a number to a negative power, you can rewrite it by dividing one by the original number with the negative sign dropped from the exponent. Because the power here is 1, you can rewrite the answer again to 1/(2x + 2y) since any number raised to the power of 1 is simply the number itself. You can't add 2x and 2y because they are two different variables.
