Question

4(3х+4)-5=-15+4(3х+5)=2х-5

Answer 1

4(3х+4)-5=-1

12х+16-5=-1

12х=-1-16+5

12х=-12

Х=-1

Ответ:х=-1

5+4(3х+5)=2х-5

5+12х+20=2х-5

12х-2х=-5-5-20

10х=-30

Х=-3

Ответ:х=-3

Answer 2

Let's solve the given equation step by step:

1. Start with the first part of the equation: 4(3x + 4) - 5 = -15.

First, distribute the 4 on the left side of the equation:

12x + 16 - 5 = -15.

2. Now, combine like terms on the left side:

12x + 16 - 5 = -15 12x + 11 = -15.

3. Next, isolate the variable x. To do this, subtract 11 from both sides of the equation:

12x + 11 - 11 = -15 - 11 12x = -26.

4. Finally, divide both sides by 12 to solve for x:

(12x)/12 = (-26)/12 x = -26/12 x = -13/6.

Now, let's check the second part of the equation: 4(3x + 5) = 2x - 5.

1. Distribute the 4 on the left side:

12x + 20 = 2x - 5.

2. Move all the terms containing x to the left side by subtracting 2x from both sides:

12x - 2x + 20 = -5.

3. Combine like terms on the left side:

10x + 20 = -5.

4. Subtract 20 from both sides to isolate x:

10x + 20 - 20 = -5 - 20 10x = -25.

5. Finally, divide both sides by 10 to solve for x:

(10x)/10 = (-25)/10 x = -5/2.

So, you have two different values for x in these two equations:

x = -13/6 and x = -5/2.
