Question

tell whether the statement below is always, sometimes, or never true. Equations like a+4=8 and 4-m=2 have exactly one solution

Answer 1

• Always

Explanation:

The equation can be described as a single linear equation in one variable with the variable on only one side of the equal sign and having a non-zero coefficient. Such an equation will always have exactly one solution. The solution can be found by simplifying the equation to the form ...

x = a

where x represents the variable, and "a" represents an appropriate constant, found by using the properties of arithmetic and equality.
