 Question 553033: Correction for problem 1. it should read as: Solve using addition to eliminate one variable. 1. -y=2x, 3x+y=20 Thanks again... You rock Alan!! 1. -y=2x, 3x+y=20 2. 4x+2y=6, 2x+y=3 Solve using Substitution to eliminate one variable. 3. y+5x=17, 4x-3y=6 4. y=-x+3, 2x=-2y+10 thanks for any help offered. Also corrected problem 4 to its proper form... So still looking for help with Problems 1 and 4. Thank you for the help!!
