Question

Simplify the expression and find its value, if x is equal to 2.
$4(2x - 1) + 3x + 11$

Answer 1

Hint: Here, we need to simplify the given expression and then we have to find the value of expression by substituting the value of x as 2.

Complete step-by-step answer:
The given expression is $4(2x - 1) + 3x + 11$
We have to find the value of the expression at $x = 2$
Now let’s simplify the expression we have
$
   = 8x - 4 + 3x + 11 \\
   = 11x + 7 \\
$
Now substitute 2 in place of x
We have $11(2) + 7$
$ = 22 + 7 = 29$
Answer is 29.

Note: In such questions simply open the bracket first by performing the specific operation as asked in the question then simplification is followed by substitution which will give us an answer.
