Answer 2

★Given :

• x = 2
• The expression 4 ( 2x - 1 ) + 3x - 11​.

★To find :

• Value of the expression.

★Solution :

We need to know :

→An expression is a sentence with a minimum of two numbers and at least one math operation.

→This math operation can be addition, subtraction, multiplication, and division.

Here,we are given an expression and also the value of the variable.Hence we substitute the value of the variable in the given expression to simplify it.

Substituting the value of x,

→4 ( 2x - 1 ) + 3x - 11​

→4(2(2) - 1) + 3(2) - 11

→4(4 - 1 ) + 6 - 11

→4 (3) + 6 - 11

→12 + 6 - 11

→18 - 11

→ 7 .

Hence,the value of the expression is 7.
