I found an answer from www. For example, When an equation is given in this form , it's pretty easy to find both intercepts x and y. The line satisfying this equation would have a gradient slope of For more information, see Intro to linear equation standard form Algebra video Khan What Is the Square Root Method?

How to Integrate the Cube Root of X. How to Solve for Sigma on a TI If you multiply by seven you get rid of this fraction. So if you multiply three and you multiply by seven. Let me just rewrite it over here. There's actually also a couple of ways that we can do this. So if you multiply. So one way to do it. So if I multiply this side by three and I multiply by seven, I have to do that to this side as well.
So this is going to be multiplied by three and multiplied by seven. So the left hand side becomes 21y. Three times seven of course is 21, we just figured that out. We would distribute the So it's gonna be 14x. And then 21 divided by seven is three times four is So just like that I was able to get rid of the fractions. And now I wanna get all the X's and Y's on one side.
So I wanna get this 14x onto the left side. So let's see if I can do that. So I'm gonna do that by. To get rid of this I would want to subtract 14x. I can't just do it on the right hand side I have to do it on the left hand side as well. So I wanna subtract 14x, and then what am I left with? Let me give myself a little bit more space. So on the left hand side I have negative 14x plus 21y. Plus 21y is equal to. Let's see and I subtracted 14x to get rid of this. And then I have this is equal to
