Answer 1

Answer:

d) 5x + 3 is not a linear equation.

• It is merely an algebraic expression as it is a combination of constants and variables.
• A linear equation is an algebraic expression which contains a statement of equality and is true for certain value(s) for the variable(s).
• Here, 5x+3 does not equate to anything, thus, it is not a linear equation.
