Question

-5( 3 - x ) = 9( x + 1)​

Answer 1

-5(3 - x) = 9(x + 1)

-15 + 5х = 9х + 9

5х - 9х = 9 + 15

-4х = 24

х = 24 : (-4)

х = -6

Відповідь: -6.

Answer 2

To solve the equation -5(3 - x) = 9(x + 1), we can begin by simplifying both sides of the equation and then solving for x. Let's go step by step:

Step 1: Distribute the -5 and 9 to the terms inside the parentheses:

-5(3 - x) = 9(x + 1) becomes: -15 + 5x = 9x + 9

Step 2: Combine like terms:

-15 + 5x = 9x + 9 can be rewritten as: 5x - 9x = 9 - (-15)

Simplifying further: -4x = 24

Step 3: Divide both sides of the equation by -4 to solve for x:

-4x = 24 x = 24 / -4 x = -6

So the solution to the equation -5(3 - x) = 9(x + 1) is x = -6.
