Question

Which vocabulary term refers to the process you can use to check whether the value x = 7 is the solution to the equation 47 - 5x = 2 (x - 1)
?

equality

inverse

solution

substitution

Answer 1

The vocabulary term that refers to the process you can use to check whether the value \( x = 7 \) is the solution to the equation \( 47 - 5x = 2(x - 1) \) is **substitution**.

In substitution, you would replace \( x \) in the equation with \( 7 \) and see if both sides of the equation are equal.
