Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given information
x = 6
Given expression
4 (2x - 1) + 3
Substitute values into the expression
=4 [2 (6) - 1] + 3
Simplify by multiplication
=4 (12 - 1) + 3
Simplify by subtraction
=4 (11) + 3
Simplify by multiplication
=44 + 3
Simplify by addition
=
