Question

(5-3x)=6 (8x+1)=-2 1,5*(1-x)=6

Answer 1

Ответ:

Пошаговое объяснение:

(5-3x)=6

3х=5-6

3х=-1

х=-1/3

(8x+1)=-2

8х=-2-1

8х=-3

х=-3/8

1,5*(1-x)=6

1-х=6*1.5

1-х=9

х=1-9

х=-8

Answer 2

Let's solve each equation step by step:

1. (5-3x) = 6

Let's start by isolating the variable x. We'll begin by moving the constant term to the other side of the equation.

5 - 3x = 6 -3x = 6 - 5 -3x = 1

Now, divide both sides of the equation by -3 to solve for x:

x = 1 / -3 x = -1/3

Therefore, the solution to the equation (5-3x) = 6 is x = -1/3.

2. (8x + 1) = -2

We'll follow the same process as before to isolate x.

8x + 1 = -2

Now, move the constant term to the other side of the equation:

8x = -2 - 1 8x = -3

Divide both sides of the equation by 8:

x = -3 / 8

Thus, the solution to the equation (8x + 1) = -2 is x = -3/8.

3. 1.5 * (1 - x) = 6

Let's simplify the equation first by distributing the 1.5 to the terms inside the parentheses:

1.5 - 1.5x = 6

Next, move the constant term to the other side:

-1.5x = 6 - 1.5 -1.5x = 4.5

Divide both sides of the equation by -1.5:

x = 4.5 / -1.5 x = -3

Therefore, the solution to the equation 1.5 * (1 - x) = 6 is x = -3.

To summarize the solutions:

(5-3x) = 6 has a solution x = -1/3. (8x + 1) = -2 has a solution x = -3/8. 1.5 * (1 - x) = 6 has a solution x = -3.
