Answer:
y = 3/5x - 2
y = -1.5x + 3.5
y = 6x - 6
Step-by-step explanation:
For equation 3x - 5y = 10:
Rearraging gives;
5y = 3x - 10
Dividing throughout by 5 gives;
y = 3/5x - 2
For equation 3x + 2y = 7:
Rearraging gives;
2y = -3x + 7
Dividing throughout by 2 gives;
y = -3/2x + 3.5
For equation 3x - 1/2y = 3:
Rearraging gives;
1/2y = 3x - 3
Multiplying throughout by 2 gives;
y = 6x - 6
