We just need to substitute in 6 whether we see an x:

(7*6) - 4*(6-6) + 12
= 42 - 4*0 + 12
=54

The value of the expression 7x – 4(6 – x) + 12, at x = 6 will be 54.

What is simplification?

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

The expression is given below.

⇒ 7x – 4(6 – x) + 12

Simplify the expression, we have

⇒ 7x – 24 + 4x + 12

⇒ 11x – 12

Then the value of the expression, at x = 6 will be

⇒ 11(6) – 12

⇒ 66 – 12

⇒ 54
