Question

1,7(a-4+0,6(6-2a)=?

Answer 1

1,7(а-4+0,6(6-2а))=1,7(а-4+3,6-1,2а)=1,7(-0,2а-0,4)=-0,34а-0,68.

Answer 2

To solve the equation 1,7(a-4+0,6(6-2a)), we can simplify it step by step.

1,7(a-4+0,6(6-2a))

First, let's distribute the 0,6 to the terms inside the parentheses:

1,7(a-4+0,6(6)-0,6(2a))

Simplifying further:

1,7(a-4+3,6-1,2a)

Now, let's simplify the parentheses by combining like terms:

1,7(-0,2a-0,4+3,6)

Next, let's distribute the 1,7 to the terms inside the parentheses:

-0,34a - 0,68 + 6,12

Combining like terms:

-0,34a + 5,44

Therefore, the simplified form of the expression 1,7(a-4+0,6(6-2a)) is -0,34a + 5,44.
