The expression 6(x - 5) means 6x - 30, and if x = 7, the value of the expression is 12.
An expression is a combination of variables, numbers, constants, and values without the use of the equation symbol (=).
6(x - 5)
Simplifying the expression:
=6x - 30
If x = 7, 6x - 30:
= 6(7) - 30
= 42 - 30 = 12
Thus, the value of the expression 6(x − 5) when x = 7 is 12.
