Question

Solve for x 2x-2+4x-5

Answer 1

-40

Explanation:

2 times negative 2 is 4 plus 4 is 8 times negative 5 is -40

Answer 2

`x=3/2=1.5`

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.

`((-2x))/(-2)=(-3)/(-2)`

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

`x=3/2=1.5`
