Question

How do you find the value of the following expression given that a=4, b=3, and c=-2?

4b-2a

a) 6
b) 5
c) 4
d) 7

Answer 1

The value of the expression 4b - 2a with a=4 and b=3 is 4 after substituting the values and simplifying the expression.

Step-by-step explanation:

To find the value of the expression 4b - 2a given that a=4, b=3, and c=-2, you need to substitute the values of a and b into the expression.

Step 1: Substitute the given values into the expression.

4b - 2a = 4(3) - 2(4)

Step 2: Perform the multiplication.

4b - 2a = 12 - 8

Step 3: Subtract to get the final result.

4b - 2a = 4

The value of the expression is therefore 4 (Option c).
