Solve this system of equations by
using the elimination method.

Answer 1

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

Answer 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

$\:$

• (2 , 2)
