drwls, is this correct,math
drawls this is from the previous post is this correct. solve the system by subtraction. 5x3y=13 4x3y=11 equation#2 woudl be 4x3y=11 3y = 4x+11 y = (4)/(3) x  (11)/(3) so now i substitute it to equation #1 5x  3((4)/(3)x

How do I do this.?(Math.)
Use the Substitution method to solve the system of equations. y  2x = 5 3y  x = 5 Solve one of the equations for x or y. Let's solve the first one for y: y  2x = 5 y = 2x  5 Now let's substitute 2x  5 for y in the second
