Question

please answer this question check whether X + 3 Y is equal to 6 and 2 x minus 3 Y is equal to 12 is consistent or not

Answer 1

2x-3y=12
x+3y=6
..................... adding
3x=18
x=6
putting in given eq

6+3y=6
3y=0
y=0

Answer 2

To find:

x + 3y = 6

x = 6 - 3y

x = - 3y + 6

To find:

2x - 3y = 12

2x = 12 + 3y

x = 12 + 3y × 2

x = 12 × 2

x = 24 + 3y

x = 3y + 24
