Answer:

The solution to the system of equations is:

x = 3/2

y = -1

Step-by-step explanation:

Given the pair of equations:

2x - 3y = 6 .....................................................................(1)

2x - 6y = 9 .....................................................................(2)

Subtract equation (1) from (2) to eliminate x

-6y - (-3y)= 9 - 6

-6y + 3y = 3

-3y = 3

Divide both sides by -3

y = -3/3 = -1

Using y = -1 in equation (1)

2x - 3(-1) = 6

2x + 3 = 6

2x = 6 - 3

2x = 3

Divide both sides by 2

x = 3/2
