Bonjour!¡
x + 2y = 2 …(1)
2x + 3y = 3 …(2)
Multiplying eq (1) by 2
2x + 4y = 4 …(3)
Sub (3) from (2)
2x + 3y - 3 -(2x + 4y - 4)
2x + 3y - 3 - 2x - 4y + 4
-y = -1
y = 1
Putting value of y in (1)
x + 2(1) = 2
x + 2 = 2
x = 2 - 2
x = 0
x + 2y = 2 …(1)
2x + 3y = 3 …(2)
Multiplying eq (1) by 2
2x + 4y = 4 …(3)
Sub (3) from (2)
2x + 3y - 3 -(2x + 4y - 4)
2x + 3y - 3 - 2x - 4y + 4
-y = -1
y = 1
Putting value of y in (1)
x + 2(1) = 2
x + 2 = 2
x = 2 - 2
x = 0
