Question

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

Answer 1

x= 4, y=3

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
