Tyrone wrote an equivalent expression for 28 + x - 2n + 7 - n - 5x + 4. his equivalent expression was -3n - 5x + 39 + x. what error did tyrone make?

a. tyrone neglected to combine the x terms.

b. tyrone added the constants instead of subtracting them.

c. tyrone neglected to add the coefficients of the n terms.

d. tyrone made an error when he added the constants.

The answer is A

Step-by-step explanation:

Answer with Step-by-step explanation:

We are given an expression:

28 + x - 2n + 7 - n - 5x + 4

We have to find its equivalent expression

On combining the like terms of the above expression

28+4+7+x-5x-2n-n

= 39-4x-3n

= -3n-4x+39

According to Tyrone the equivalent expression was:

-3n - 5x + 39 + x

The error Tyrone made was:

A. Tyrone neglected to combine the x terms
