Could someone show me how to finish this problem?
The problem is that I have to do solving systems, and the method I chose was graphing. The equation is: 3x – 9y = 3 6x – 3y = -24 What is the slope and y-intercept of the equations? And also could you graph them on my graph.
you don't need a graph just multiply the firt equation with -2 and add up the 2 eqns you get a value for y then substitute it in anyone of the 2 eqns u get a vlaue of x thus the(x,y) is the sln
3x-9y=3. Multiplied by -2 gives -6x+18y=-6. 6x-3y=-24. So... (-6x+18y)+(6x-3y)=-24+(-6). Break the patantheses and you will find y. Then x is easily found in kne of the equations. Thats what lah said. I tried to explain.
