Best ResponseYou've already chosen the best response.0Okay let me help you out then. If we move over the 3y onto the right hand side then we get \[x=13y\]

Best ResponseYou've already chosen the best response.0This form of solving a system of equations is known as substitution. Reason being, we can now substitute the value for x we have now into the second equation, hence eliminating the other variable.

Best ResponseYou've already chosen the best response.02x+3y = 1 2x = 13y x = (13y)/2 3(13y)/2 + 2y = 6 39y + 4y = 12 5y = 15 y = 3 2x+3(3) = 1 2x + 9 = 1 2x = 8 x = 4 i hope this helps!
