They are both on the same line. | Substitution 2x+y=5 = y=5-2x x-y=1 = x-(5-2x)=1 x-5+2x=1 3x-5=1 +5 +5 3x=6 x=2 y=5-2(2) y=1 Elimination 4a+26=15 4a+26=15 +-2a-2a=-7 -1 *(2a+26=7) ----------------- 2(4)+26=7 2a=8 8+26=7 a=4 26=-1 b=-1/2 Special Case -2(3p-6a=6) -6p+12q=-12 3(2p-4q=4) +6p-12q=12 ----------------- 0+0=0 0=0 8 Graphing My favorite process is substitution because, I have been doing the substitution process since I was in the 7th grade, and its the least time consuming process there is. |
