Answer 1

-2*(-1.5с-6)+(7-3с)=-2*(-1,5с)-(-2)*6+7-3с= 3с+12+7-3с=19

Answer 2

To solve the given expression, let's break it down step by step:

-2*(-1.5c-6) + (7-3c)

Step 1: Simplify the expression within the parentheses (-1.5c-6) by distributing the -2:

2(1.5c+6) + (7-3c)

Step 2: Simplify the expression within the parentheses (1.5c+6) by distributing the 2:

3c + 12 + (7-3c)

Step 3: Simplify the expression within the parentheses (7-3c):

3c + 12 + 7 - 3c

Step 4: Combine like terms:

(3c - 3c) + 12 + 7

Step 5: Simplify:

0c + 19

Step 6: Simplify further:

19

Therefore, the solution to the given expression -2*(-1.5c-6) + (7-3c) is 19.
