Answer 2

Answer:

$x=3/2=1.5$

Step-by-step explanation:

So we have the equation:

$2x-2=4x-5$

And we want to solve for x. To do this, we need to first isolate the x-variable. So, start by adding 2 to both sides:

$(2x-2)+2=(4x-5)+2$

The 2s on the left cancel:

$2x=4x-3$

Now, subtract 4x from both sides:

$(2x)-4x=(4x-3)-4x$

The 4xson the right cancel:

$-2x=-3$

Now, divide both sides by -2.

$\frac{(-2x)}{-2}=\frac{-3}{-2}$

The negatives cancel. The 2s on the left cancel. Therefore:

$x=3/2=1.5$
