Solve the given simultaneous equations : 2x + 3y = 17 ; 3x - 2y = 6

34kurt

Answer:

x= 4, y=3

Step-by-step explanation:

2x + 3y = 17

3x - 2y = 6

----------

If we double the first and triple the second equation, and add up, we can get rid of y:

4x+6y= 34
+
9x - 6y= 18
-----------------
13x= 52
x= 4

Then it is easy to find the value of y:

2*4+3y= 17
3y= 9
y= 3

Answer is: x= 4, y=3
