Question
1.Solve by the substitution method.3x - 5y = 15 y = 2x + 4 2. Solve by the elimination method.2x - 5y = 1 3x
1.Solve by the substitution method.3x - 5y = 15
y = 2x + 4
2. Solve by the elimination method.2x - 5y = 1
3x - 4y = -2
3. Solve by the substitution method.2x + 8y = 1
x = 2y
4. Solve by the substitution method.x + y = 3
2x + 3y = -4
