Best ResponseYou've already chosen the best response.0just flip it to the other side y=3x+3 becomes y3/3=x and y=x1 becomes y+1=x

Best ResponseYou've already chosen the best response.0y = 3x + 3......so now we substitute 3x + 3 in for y in the other equation y = x  1 3x + 3 = x  1  subtract x from both sides 3x  x + 3 = x  x  1  combine like terms 2x + 3 = 1  subtract 3 from both sides 2x + 3  3 = 1  3  combine like terms 2x = 4  divide both sides by 2 2/2x = 4/2 x = 2 now we sub in 2 for x in either of the original equations to find y y = 3x + 3 y = 3(2) + 3 y = 6 + 3 y = 3 now we check.. y = x  1 3 = 2 1 3 = 3 (correct) so your solution is : (2,3)
