Question

1,7(a+4)+0,6(6-2a) 1,5(8x-6y)-2,4(5y-3x)=

Answer 1

1,7а+6,8+ 3,6-1,2а= 0,5а+10,4

12х-9у-12у+7,2х= 19,2х-21у

Answer 2

It seems like you've provided two equations with expressions involving variables. To help you further, I can simplify and solve the equations for you. Let's start with the first equation:

1. $1.7(a+4) + 0.6(6-2a)$

Simplify the terms inside the parentheses:

$1.7a + 1.7 \cdot 4 + 0.6 \cdot 6 - 0.6 \cdot 2a$

$1.7a + 6.8 + 3.6 - 1.2a$

Combine like terms:

$0.5a + 10.4$

So, the first expression simplifies to $0.5a + 10.4$.

Now, let's move on to the second equation:

2. $1.5(8x-6y) - 2.4(5y-3x)$

Simplify the terms inside the parentheses:

$1.5 \cdot 8x - 1.5 \cdot 6y - 2.4 \cdot 5y + 2.4 \cdot 3x$

$12x - 9y - 12y + 7.2x$

Combine like terms:

$19.2x - 21y$

So, the second expression simplifies to $19.2x - 21y$.

Now, you've got the simplified forms of the two expressions. If you want to equate them, you would have:

$0.5a + 10.4 = 19.2x - 21y$

Please provide more context or information if you're looking for a specific solution or further manipulation of this equation.
