Question

4 x minus 6 Y is equal to 12 and 3 X + 6 Y is equals to 18​

Answer 1

Answer:

Step-by-step explanation:

4x-6y=12

3x+6y=18

Add the equations

4x-6y+3x+6y=12+18

7x=30

x=30/7

4(30/7) -6y=12

(120/7)-6y=12

-6y=12-(120/7)

-6y=(84/7)-(120/7)

-6y=-36/7

6y=36/7

y=36/(7×6) =6/7

Answer:x=(12/7), y=(6/7)
