Question

-(4-2х)+(5-3х)+(9-х)=-(х+5)

Answer 1

Ответ:

$-(4-2x)+(5-3x)+(9-x)=-(x+5)\\-4+2x+5-3x+9-x=-x-5\\10-2x=-x-5\\-2x+x=-5-10\\-x=-15\\x=15$

x=15

Answer 2

Let's solve the equation step by step:

Given equation: -(4 - 2x) + (5 - 3x) + (9 - x) = -(x + 5)

Distribute the negative sign: -4 + 2x + 5 - 3x + 9 - x = -(x + 5)

Combine like terms on the left side: (2x - 3x - x) + (-4 + 5 + 9) = -(x + 5) -2x + 10 = -(x + 5)

Multiply both sides by -1 to remove the negative sign on the right side: 2x - 10 = x + 5

Subtract x from both sides: 2x - x - 10 = 5 x - 10 = 5

Add 10 to both sides to solve for x: x = 5 + 10 x = 15

So, the solution for the equation is x = 15.
