Answer 2

Problem Statement

The given expression is: 1.5(8x - 6y) - (5y - 3x) * 2.4. Let's simplify and solve this expression.

Solution

To simplify the expression, we will apply the distributive property and perform the necessary calculations.

1.5(8x - 6y) - (5y - 3x) * 2.4

First, let's simplify the expression inside the parentheses: 8x - 6y

Next, let's simplify the expression inside the second set of parentheses: (5y - 3x)

Now, let's apply the distributive property: 1.5 * 8x - 1.5 * 6y - (2.4 * 5y - 2.4 * 3x)

Simplifying further: 12x - 9y - (12y - 7.2x)

Now, let's distribute the negative sign inside the second set of parentheses: 12x - 9y - 12y + 7.2x

Combining like terms: (12x + 7.2x) - (9y + 12y)

Simplifying further: 19.2x - 21y

Therefore, the simplified expression is 19.2x - 21y.
