from the second equation you can write y as x - 3. Now plug this value of y in the first equation.

anonymous · Answer

Eq 1: 4x + 2y = 12
Eq 2: x - y = 3
Add y - 3 on both sides for eq 2
This gives you:
x - y + y - 3 = 3 + y - 3
same as: x - 3 = y
Now replace y by x - 3 in first equation:
4x + 2(x - 3) = 12

4x + 2x - 6 = 12
=> 6x = 18
=> x = 3
