Answer 3

To evaluate the expression 6x - 3[4-y] with x = -1 and y = -3, let's substitute the values and simplify the expression step by step:

Step 1: Substitute the values of x and y into the expression.

6x - 3[4-y] becomes 6(-1) - 3[4-(-3)].

Step 2: Simplify the expression inside the square brackets.

4 - (-3) becomes 4 + 3, which is equal to 7.

Now the expression becomes 6(-1) - 3[7].

Step 3: Simplify the expression within the square brackets.

3 multiplied by 7 is equal to 21.

Now the expression becomes 6(-1) - 21.

Step 4: Simplify the remaining expression.

6 multiplied by -1 is equal to -6.

Now the expression becomes -6 - 21.

Step 5: Subtract the numbers.

-6 - 21 is equal to -27.

Therefore, the evaluated expression is -27.
