Answer 1

Answer:

don't know if anybody tells so you also tell me

Answer 2

Answer:

x=2.875

y= 3.75

Step-by-step explanation:

1. 3x = 12- y

• x = (12- y)/3
• x = 4 - 0.3y

6x= 6+3y

• where x = 4 - 0.3y
• 6(4 - 0.3y) = 6 + 3y
• 24 - 1.8y = 6 + 3y
• 24 - 6 = 3y +1.8y
• 18 = 4.8y
• y= 18/4.8
• y= 3.75

where x = 4 - 0.3y

x = 4 - 0.3(3.75)

x = 4 - 1.125

x = 2.875
