Respuesta :

Maria combined all of the factors, which were not all like terms. She should’ve did -4n+9n and 3-4 to get 5n-1

The error that Maria did was combining all the factors in the algebraic expression without collecting the like terms to a particular side to solve for the variable (n).

What is an Algebraic expression?

Algebraic expression involves solving numbers with variables with the use of arithmetic operations e.g.

  • Addition
  • Subtraction
  • Multiplication
  • Division

Claim:

Maria Said that:

  • -4n + 3 + 9n - 4 = 4n

If we ignore the like terms and assume all numbers have a variable (n);

Then, we have:

  • -4n + 3n + 9n - 4n = 4n
