Question

Раскрыть скобки и привести подобные слагаемые: (1,3x - 4) - ( 6+ 2,7x)

Answer 1

1.3х-4-6-2.7х= -0.4х-10

Answer 2

To expand the expression and combine like terms, follow these steps:

Step 1: Distribute the negative sign in front of the second parentheses. Step 2: Combine like terms.

Let's proceed with the calculations:

Step 1: (1 + 3x - 4) - (6 + 2.7x)

Step 2: Combine the constants (numbers without variables) first and then the terms with 'x'.

1 - 4 = -3

Now, the expression becomes:

(-3 + 3x) - (6 + 2.7x)

Next, let's combine the terms with 'x':

3x - 2.7x = 0.3x

So the final simplified expression is:

-3 + 0.3x

And that's the result after expanding the parentheses and combining like terms.
