How many solutions does this have? x+2y=3 x-y=6

x = 5 , y = -1

Step-by-step explanation:

x + 2y = 3........(equation 1)

x - y = 6..........(equation 2)

make x the subject of the formula in (equation 1)

x = 3 - 2y

substitute for x in (equation 2)

3x - y = 6

(3- 2y) - y = 6

3 - 2y - y = 6

3 - 3y = 6

-3y = 6 - 3

substitute for y in (equation 1)

x = 3 - 2y

x = 5

because 1.2 isnt half of 6 duh

i dont know if you cant find a way its best to actually add all of them start from 105 tho
