Question

3х-1+1 = 10х -15+1 3х = ?

Answer 1

3x-1+1 = 10x-15+1

3x-10x=-15+1+1-1

-7x=-14

x=2

Answer 2

Let's solve for the value of x in the equation:

3x - 1 + 1 = 10x - 15 + 1

First, simplify the equation by combining like terms on both sides:

3x = 10x - 15

Now, let's isolate the variable x on one side of the equation. Subtract 10x from both sides:

3x - 10x = -15

-7x = -15

Finally, solve for x by dividing both sides by -7:

x = (-15) / (-7)

x ≈ 2.142857

So, the value of x is approximately 2.142857.
