It seems like there might be a typo or missing operators in your equation "x 2x 7." If you meant to write an equation, please clarify, such as "x + 2x = 7" or "x * 2x = 7." If it's "x + 2x = 7," then combining like terms gives you "3x = 7," leading to the solution ( x = \frac{7}{3} ). If it's another equation, please provide the correct format for a more accurate answer.

What is math equation to represent?
In mathematics, an equation is a mathematical formula that expresses the equality of two expressions, by connecting them with the equals sign =. Example: 2x + 3 = 7 In this equation, 2x + 3 becomes included as one expression, and 7 is another expression. This equation declares that the two expressions need to be identical. To solve the equation for x, you'd do following steps: Subtract 3 from both sides of the equation the equation: 2x + 3 - 3 = 7 - 3 2x = 4 Divide both sides by 2: 2x/2 = 4/2 x = 2 Therefore, the solution to 2x + 3 = 7 is x = 2.
What equation is 8-2(x plus 7) equal to?
To simplify the equation (8 - 2(x + 7)), first distribute the -2: [8 - 2x - 14.] Then combine like terms: [8 - 14 - 2x = -6 - 2x.] So, the equation (8 - 2(x + 7)) is equal to (-6 - 2x).

What is the equation of 2x 1 equals 7?
im assuming your equation is 2x + 1 = 7 in this case you need to find what x equals 2x + 1 = 7 2x + 1 - 1 = 7-1 2x = 6 x = 3 put it back into the equation to check if your answer is correct 2(3) + 1 = 7 6 + 1 = 7 7 = 7 Correct! if your equation is 2x - 1 = 7 x = 4 check it 2(4) - 1 = 7 8 - 1 = 7 7 = 7 Correct! if your equation is 2x1 = 7 x = 7/2 check it 2(7/2)1 = 7 2(7/2) = 7 2 * 7 / 2 = 7 14/2 = 7 7 = 7 Correct! hope i got your equation right. if not you can message me on my message board to get more help.
