- Substitution Solutions
- Elimination Solutions
Use Graphing to Find the Solutions
- y = 2x - 4
y = -8x + 46 - y = -x + 3
y = x -3 - y = -2x - 3
y = 8x - 8 - y = -4x + 54
y = -5x + 65 - y = 5x + 2
y = 5x -3
Use Substitution to Find the Solutions
- y = 1 + 5x
12y – 12 = 60x
- x = 4
3x + y = 10 - x = -7 + ¼y
y = -2x – 2 - y = 3x + 5
x – y = 6 - y = 5x + 2
y + 2x = 5
Use Elimination to Find the Solutions
- x + 10y = 85
x + 15y = 125 - x – 3y = 25
x – 2y = 21 - 96x + 30y = 64
-21x + 7y = -14 - x – 16y = -31
x + 48y = 49 - ½ y – x = 1
y – 2x = -5
