To write an equivalent expression, you need to combine like variables and constants separately.

For example, the expression, w + 10 + w – 4, is equivalent to this, 2w + 6, after the like variables and constants have been combined.

What is an equivalent expression?

An equivalent expression is a representation of equal values, which may not look alike.

Mathematical expressions are made up of constants and variables.

What are the differences between variables and constants?

The main differences between variables and constants in any system of equations are:

  • Constants have known values, unlike variables.
  • A constant does not change its value while a variable changes its value depending on the equation.
  • Numbers are used in writing constants while variables are written in letters or symbols.

Data and Calculations:

w + 10 + w - 4

collecting like terms together, we have:

1w + 1w + 10 - 4

= 2w + 10 - 4

= 2w + 6

Thus, the expression, w + 10 + w – 4, is equivalent to this, 2w + 6, after the like variables and constants have been combined.
