**Bosnian**, Monday, March 19, 2012 at 12:09am2 x – 3 y = 10 Multiply both sides by 2

4 x - 6 y = 20

5 x + 2 y = 6 Multiply both sides by 3

15 x + 6 y = 18

4 x - 6 y = 20

+

15 x + 6 y = 18

----------------

4 x + 15 x - 6 y + 6 y = 20 + 18

19 x = 38 Divide both sides by 19

x = 38 / 19

x = 2

To get the value of y you need to use the substitution method.

Substitute x = 2

into equation

2 x - 3 y = 10

2 * 2 - 3 y = 10

4 - 3 y = 10

- 3 y = 10 - 4

- 3 y = 6 Divide both sides by - 3

y = 6 / - 3

y = - 2

**Margena**, Sunday, April 7, 2013 at 7:55pmThe point of intersection of the graphs of the equations of the system

Ax – 4y = 9

4x + By = –1

is (–1, –3). Explain how to find the values of A and B, then find these values.
