is 2x - 5 = 5 = 7x = 3 a linear equation

no, all I see is a contradiction

(I see a bunch of "bouncing" equal signs, which suggest that 5 = 3, which would be a new breakthrough in mathematics)

No, the equation you provided, "2x - 5 = 5 = 7x = 3," is not a linear equation. A linear equation is an equation of degree 1, where the variables are raised to the power of 1 and do not have any exponential terms or other variables multiplied or divided by them.

In the equation you provided, there are multiple equal signs, which is not a valid form for an equation. Additionally, it seems like there might be multiple variables (x and 7x), and the equation is not properly separated or balanced.

To write a linear equation, you typically have one variable, coefficients (numbers multiplying the variables), constants (numbers without variables), and operators like addition and subtraction. An example of a linear equation is: "3x - 4 = 2."

To determine if an equation is linear, you should ensure that it follows the basic rules and structure of a linear equation.
