Question

-х-4+5(х+3)=5(х-1)-2

Answer 1

-x-4+5x+15=5x-5-2

-x+5x-5x=-5-2+4-15

-x=-5-2+4-15/:(-1)

x=5+2-4+15

x=18

Answer 2

$- x - 4 + 5x + 15 = 5x - 5 - 2 \\ 4x + 11 = 5x - 7 \\ 4x + 11- 5x + 7 = 0 \\ - x + 18 = 0$

$- x = 0 - 18 \\ - x = - 18 \\ x = 18$

Ответ:х=18

Answer 3

To solve the given equation, let's follow the steps below:

1. Distribute the multiplication on both sides of the equation.
2. Simplify and combine like terms.
3. Isolate the variable (x) on one side of the equation.
4. Solve for x.

Let's proceed with the steps:

Step 1: Distribute the multiplication -х - 4 + 5(х + 3) = 5(х - 1) - 2

Expanding the multiplication: -х - 4 + 5х + 15 = 5х - 5 - 2

Step 2: Combine like terms Now, let's combine the like terms on each side of the equation:

(5х - х) + (15 - 4) = (5х - 5) - 2

Simplifying: 4х + 11 = 5х - 7

Step 3: Isolate the variable (x) Next, let's get all the x terms on one side and the constant terms on the other side of the equation:

4х - 5х = -7 - 11

Simplifying: -x = -18

Step 4: Solve for x To solve for x, divide both sides of the equation by -1:

x = -18 / -1

Simplifying: x = 18

The solution to the equation is x = 18.
