What is the value of y in LMNO? https://www.connexus.com/content/media/456845-1282011-25520-PM-371715253.png
(1) y = 3x (2) 6x = y + 12 so by substitution: 6x = (3x)+12 3x=12 x=4 Substitute again into equation 1: y=3(4) y=12
Well....letting the person work it out or ask questions may have been better?
