2(15x-4-3(10-3))

2(15x-4-30x+9)

2(-15x+5)

2(-5(3x-1))

-10(3x-1)

Answer 3

To simplify the expression 2 × (15x - 4) - 6 × (10x - 3), you can use the distributive property to expand and then combine like terms. Here's how you can do it step by step:

1. Distribute the constants (2 and 6) to the terms inside the parentheses:

2 × 15x - 2 × 4 - 6 × 10x + 6 × 3

2. Now, perform the multiplications inside each term:

30x - 8 - 60x + 18

3. Combine like terms (the x terms and the constants):

(30x - 60x) + (-8 + 18)

4. Combine the x terms:

-30x + 10

So, the simplified expression is:

-30x + 10
