Best ResponseYou've already chosen the best response.0Are you trying to solve this algebraically? If so, you should subtract 2x from both sides: \[x5=7\] Then add 5 to both sides \[x=12\] Test this to make sure it works: \[3(12)5=2(12)+7\] \[36 5=24+7\] \[31=31\] Yay! :D

Best ResponseYou've already chosen the best response.0I would strongly recommend graphing this to help understand that it's really the intersection of two lines. Let \[y_1=3x5\] and \[y_2=2x+7\] You will see that they intersect at the exact (x,y) coordinate of (12,31) :)

Best ResponseYou've already chosen the best response.0(on a TI calculator to find the intersection you may have to zoom out and then type 2nd > calc > intersect. ) Hope this helps!

Best ResponseYou've already chosen the best response.0once I intersect I get x=12 and Y=31 on the TI
