Answer:

  • (2, 2)

Step-by-step explanation:

Add up the equations, it will eliminate x as variable:

  • 3x + 6y - 3x + 4y = 18 + 2
  • 10y = 20
  • y = 2

Find the value of x:

  • 3x + 6*2 = 18
  • 3x + 12 = 18
  • 3x = 6
  • x = 2

Given : -

  • 3x + 6y = 18 ... (1)
  • -3x + 4y = 2 ... (2)

To find : -

  • Solution x and y?

Solution : -

3x + 6y = 18

-3x + 4y = 2 +

10y = 20

  • y = 20/10 = 2

3x + 6y = 18

3x + 6(2) = 18

3x + 12 = 18

3x = 18 - 12

3x = 6

  • x = 6/3 = 2
