Question

1)3х-1=-8 2)3х=-1 3)-1*х=5

Answer 1

3x = -8+1 = -7
x = 7:3
x= 2.(3)

3x = -1
x = -1:3
x = -0.(3)

-1*x = 5
x = 5:(-1)
x= -5

Answer 2

Let's solve each equation step by step:

1. 3x - 1 = -8

To solve for x, we need to isolate the variable on one side of the equation. We can do this by adding 1 to both sides and then dividing by 3:

3x - 1 + 1 = -8 + 1 3x = -7

Now, divide both sides by 3 to get the value of x:

x = -7 / 3

2. 3x = -1

To solve for x, we need to isolate the variable, which is already on one side of the equation. We can do this by dividing both sides by 3:

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

3. -1 * x = 5

To solve for x, we need to isolate the variable. The coefficient of x is -1, so we can solve for x by dividing both sides by -1:

(-1 * x) / -1 = 5 / -1 x = -5

So, the solutions to the equations are:

1. x = -7 / 3
2. x = -1 / 3
3. x = -5
