Answer:

-6

Step-by-step explanation:

Evaluate the expression:

 Substitute a = -3 and b = -2 in the expression.

4a - 3b = 4*(-3) - 3 * (-2)       {Multiply 4 & (-3) and multiply (-3) & (-2)}

            = -12 + 6  {When two numbers have different sign, subtract and the result will have the bigger number sign. Here, bigger number is 12 and its sign is negtive}

            = -6
