using elimination method
2x + 3y = 6 -----(1)
-
x + 3y = 12-------(2)
———————
x = 12
substitute x as 12 into equation (1) or (2), let's choose equation (1)
2(12) + 3y = 6
24 + 3y = 6
collect like terms
3y = 6 - 24
3y = 18
divide both sides by 3 ( to make y the subject of formula )
3y = 18
— —
3 3
y = 6
therefore X = 12 and y = 6
Hope this helps eh
Good luck ✅.
