(x -1)(x +4) = 0
x² +3x -4 = 0 . . . . . . probably the form you're looking for
You first need to make sure the denominators are equal, then when they are, you can add/subtract the numerators. Then you can place the result over the common denominator.
I hope this helps! :)
3+5=8
8/20 =.4
.4 goes to 40% bc you move the decimal over twice

And we want to solve for x. In other words, we want to isolate the x-variable.
So, add 2y to both sides of the equation.

On the left, the 2y cancel. Simplify the right:

And we're done!
