Question

evaluate the expression when a = 6 and x = -5. 4a - x

Explanation:

Step1: Substitute the values of \(a\) and \(x\) into the expression.

We know \(a = 6\) and \(x=- 5\), so substitute them into \(4a - x\), we get \(4\times6-(-5)\).

Step2: Calculate the multiplication and subtraction.

First, calculate \(4\times6 = 24\), then calculate \(24-(-5)\). According to the rule of subtracting a negative number, \(24-(-5)=24 + 5=29\).

Answer:

\(29\)
