Answer 2

Simplifying the Expression

To simplify the given expression -3*(4-6x)-4*(-5a+2x), we can follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

First, let's simplify the expression inside the parentheses: - -3*(4-6x) becomes -3*4 + 3*6x - -4*(-5a+2x) becomes 4*5a - 4*2x

Now, we can simplify further: - -3*4 + 3*6x simplifies to -12 + 18x - 4*5a - 4*2x simplifies to 20a - 8x

Finally, we can combine the simplified expressions: - The original expression -3*(4-6x)-4*(-5a+2x) simplifies to -12 + 18x - 20a + 8x

Therefore, the simplified expression is -12 + 26x - 20a.
