Answer 1

Ниже основное решение. Ответ -10

Answer 2

Ответ:

9(3(x+1)-2x)=7(x+1)

9(3x+3-2x)=7x+7

27x+27-18x=7x+7

9x+27=7x+7

9x-7x=7-27

2x=-20

X=-20/2

X=-10

Answer 3

To solve the equation 9(3(x+1)-2x) = 7(x+1), follow these steps:

Step 1: Distribute the multiplication on both sides of the equation: 9(3x + 3 - 2x) = 7x + 7

Step 2: Simplify the expressions inside the parentheses: 9(x + 3) = 7x + 7

Step 3: Distribute the multiplication on the left side: 9x + 27 = 7x + 7

Step 4: Move all the x terms to one side of the equation and the constant terms to the other side: 9x - 7x = 7 - 27 2x = -20

Step 5: Isolate x by dividing both sides by 2: x = -20 / 2 x = -10

So the solution to the equation is x = -10.
