Question

Check whether the pair of equations x+3y = 6 and 2x – 3y = 12, is consistent,

If so, solve for x & y.​

Answer 1

Answer:

x+3y=6-(i)

2x-3y=12(ii)

Adding (i) and (ii)

x+3y=6

+2x-3y=12

_________

3x=18

x=18/3

x=6

put x=6 in equation (i)

x+3y=6

6+3y=6

3y=6-6

3y=0

y=0/3

y=0

therefore, x=6,y=0
