I really need help with this I don’t understand
mamaluj [8]

Answer:

Step-by-step explanation:

There is not possible solution in the real number system or the complex field.

Oddly, before I answer your question, I would point out that the equation given is a perfectly legitimate equation in some computer languages. It has the meaning of

  • Take the current value in memory location x
  • Subtract 5 from it.
  • Put the new result in memory location x.

But that is not what you are being asked about.

The blank you could put in 4

so 4 = 4 - 5

4 = - 1

The second blank will give you the result of 4 = - 1 which can't be true in a million years.

What is the constant expression of 3m+7
qwelly [4]
The constant in an algebraic expression is the only term that cannot be changed. 

Terms with variables are not constants as their values can changed as the variables change.

Our equation is 3m+7

M is a variable. Therefore the term '3m' is not the constant.

This leaves us with the term '7'. There is no variable present in this term. 

'7' is the constant in this equation.
