 Question 170305This question is from textbook Intro Algebra : This problem requires us to use the substitution method, or the elimination method. Which do you think is best and if you could explain the steps. y = 2/5x - 7 y = 2/5x + 4This question is from textbook Intro Algebra Answer by checkley77(12569)   (Show Source): You can put this solution on YOUR website!y=2/5x-7 y=2/5x+4 USING SUBTRACTION. ----------------------- 0=0-7+4 0=-3 NO UNIQUE SOLUTION FOR X OR Y. IF PLOTTED THESE 2 LINES WOULD BE PARALLEL. (graph 300x200 pixels, x from -26 to 25, y from -20 to 20, of TWO functions 2x/5 -7 and 2x/5 +4).
