Answer:

m = 3.97

Explanation:

Your equation is written as a "one-step" linear equation.

m -2 = 1.97

It is solved by adding 2 to both sides of the equation. (This is the "one step.")

m -2 +2 = 1.97 +2

Simplifying gives ...

m = 3.97

_____

If this is supposed to be an equation where -2 is a exponent, then the rules related to exponents apply. In plain text, this would be written m^-2 = 1.97.

`m^(-2)=1.97\\\\(1)/(m^2)=1.97\qquad\text{write using a positive exponent}\\\\(1)/(1.97)=m^2\qquad\text{multiply by $m^2/1.97$}\\\\\sqrt{(1)/(1.97)}=m\approx0.71247050\qquad\text{take the square root}`
