Question

To eliminate ( y, text { we have to make the coefficients of } y text { in ( } i) ) and (ii) equal. Multiplying (i) by ( 3, ) we get
[
9 x+6 y=33
]
Multiplying (ii) by ( 2, ) we get
[
4 x+6 y=8
]
Subtracting (iv) from (iii), we have
[
begin{array}{ll}
& 5 x=25
therefore & x=5
end{array}
]

# Solve the equations 3x +2y=11 2x + 3y=4
