Answer: 47
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:
<u>Given information</u>
x = 6
<u>Given expression</u>
4 (2x - 1) + 3
<u>Substitute values into the expression</u>
=4 [2 (6) - 1] + 3
<u>Simplify by multiplication</u>
=4 (12 - 1) + 3
<u>Simplify by subtraction</u>
=4 (11) + 3
<u>Simplify by multiplication</u>
=44 + 3
<u>Simplify by addition</u>
=
