Answer 1

Ответ:

7⋅(6x−3)−6⋅(7x+3)=−39.

42x-21-42x-18=-39

42x-42x=-39+18+21

x=0

Answer 2

To solve for the value of x in the given equation, we need to simplify and solve step by step. Here's the process:

Given equation: 7(6x - 3) - 6(7x + 3) = -39

Step 1: Distribute the numbers outside the parentheses: 42x - 21 - 42x - 18 = -39

Step 2: Combine like terms on both sides of the equation: (42x - 42x) + (-21 - 18) = -39 0x - 39 = -39

Step 3: Simplify the equation: -39 = -39

Since the equation simplifies to a true statement, it means that the equation is true for all values of x. In other words, the original equation doesn't have a unique solution for x. Any value of x will satisfy the equation.

Therefore, the solution to the equation 7(6x - 3) - 6(7x + 3) = -39 is all real numbers x.
