Question

I need the linear equations for this following questions

3x-5y=10

3x+2y=7

3x-1/2y=3

Answer 1

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
